Accordance Bible Software is one of the best investments a seminary student can make!

• I heartily recommend it to all my Greek students, masters, and doctoral students.

• For the advanced student/scholar, Accordance makes possible profound exegetical research by enabling complex grammatical searches in Greek and Hebrew texts; and for the beginner, it facilitates biblical languages learning.

• Preachers and teachers will find Accordance's graphics modules, maps, and timelines to be a goldmine!

• Itinerant and international workers can take their whole library with them and access these resources on their computer or iOS device.

• You can customize WorkSpaces for specific types of research; and users can even build their own tools and sets of user notes.

I would encourage every student beginning in ministry to start out with Accordance!

Accordance has been the game-changer for me as I work on my dissertation and begin my teaching career. It was great as a pastor, but it has been indispensable as a scholar! I recommend Accordance to all of my pastor-friends, students, etc. It's simply excellent on all fronts, including your commitment to updating the application regularly. I felt safe investing money in this software because I believe it will be around for a long time.

I have been a user of Accordance for many years, and I’ve learned that the right software can improve your study, empower your teaching, and give you access to an extensive library that would cost more than most of us could afford if purchased in printed form. As a student at Gordon Conwell Theological Seminary, as a youth pastor at Refuge Temple Church in Boston, and as a traveling evangelist, Accordance is a must-have!

I love using Accordance in the classroom! I used it tremendously throughout my PhD program. My dissertation topic was in the Aramaic Targums, and you guys have the most extensive targumic collection that I’m aware of, especially with the Neofiti marginal notes. Thanks for all the work you do, and I’ll continue to promote Accordance to my students!

Adam Howell

Adjunct Professor of Biblical Studies at Boyce College, The College at Southern

I have used Accordance for more than 10 years for personal Bible study and message preparation. I even used it when I wrote my first book, Strong and Courageous, A Survivor’s Facebook Journey Through Breast Cancer, and Accordance was one of my ‘go-to’ sources when preparing Running on Empty, A Personal Reflection Retreat Guide. Today, it continues to be a valued resource that I use on a weekly basis.


Drenda Howatt

Author and Speaker, Portland, Oregon

I always use the most updated version of Accordance. What I like? Fair pricing. Fairly simple to use with a little help from support. You can buy what you need and want. Better yet? While working on my Ph.D., it has helped tons! I have the Greek and Latin and Hebrew text in front of me all the time. The parsing is an excellent feature, especially since my primary goal is not to teach these languages, but to use them. I don't have to constantly review what I'm supposed to have memorized many, many years ago.


Floyd Schneider

Associate Professor of Intercultural Studies, Moody Bible Institute/Spokane, Washington

When I research the Bible for my AuthorTalk interviews, as well as for my own study, I use the software package that I think is the best in the business. It is called Accordance Bible Software, published by OakTree Software. If you are still digging through Bibles and resource materials one at a time the old-fashion way, then you are in for a treat. This software could become your best friend.​



Ron Way

Author of The Disciple: The Writing of the First Gospel, and Host of www.AuthorTalk.audio

I really appreciate the Accordance programme. I use it every week in sermon preparation. It is basically open on my desk top all the time. Being solidly based on the Greek and Hebrew Texts encourages careful exegesis. I’m only sorry that it was not available when I was at college and the years following for it makes working in the Hebrew text manageable in a busy parish ministry. Having the text of Scripture keyed into first class tools like the Bible dictionary enables me to travel to conferences with my library in my laptop.

Phillip Jensen

Dean of St Andrew’s Cathedral, Sydney

Accordance is an indispensable teaching and learning tool. I started using it as a graduate student and was hooked on the free demo version. I was using another product but was sold on the interface: simple, elegant and efficient. Accordance was also cost effective, allowing me to buy only what I needed and could afford. My students love Accordance and find that they are able to use it from the moment they learn their Hebrew and Greek letters.

I particularly appreciate the ability to customize my collection of Accordance modules to fit my research and teaching needs. Their library holds a vast array standard scholarly reference tools in an easy to use  platform. Accordance also provides some of the best technical and customer support I have ever received, and excellent user-friendly instructional materials. My faculty does require Accordance for Macintosh users. I highly recommend Accordance for graduate and seminary students, pastors and professors.

Wil Gafney, Ph.D.

Associate Professor of Hebrew and the Scriptures of Israel The Lutheran Theological Seminary at Philadelphia

Twenty years ago I first saw the Hebrew Bible appear on my computer screen. Since that time Bible software has matured from a curiosity to a necessity, and Accordance is clearly the best of the bunch. Whether primary texts, reference tools, or secondary studies, they are now on the hard drive of my laptop and accompany me from my study, into the classroom, on my travels, and even to my phoneless, email-less, backwoods cabin.

A library full of resource materials, many of which were difficult to find in all but the very best research libraries, is ready to aid my curiosity as I seek to understand the ancient cultures and texts that are the focus of the Biblical Studies student.

Martin Abegg

Ben Zion Wacholder Professor of Dead Sea Scrolls Study, Trinity Western University, Langley, BC

For biblical scholars and students who are Mac users, there is no need to look further than the constantly evolving and resolutely powerful Accordance Bible Software from OakTree software.

I have used this product since its inception. It continues to move from strength to strength, providing simple and complex search resources for biblical texts in Hebrew, Aramaic, and Greek; Second Temple Judaism and post-biblical Jewish texts (including Mishna, Qumran, and the Targums) in Aramaic and Hebrew, and a host of other Bibles and classical sources. Many or most of these are grammatically tagged.

You can also add on modules like the classic Brown Driver Briggs Hebrew-Aramaic lexicon (the famous 'BDB') and the fabulous Koehler-Baumgartner dictionary. I have not even kept up with OakTree Software's recent forays into Bible Atlases and Photo Guides, but I've seen enough to know that I'll be impressed when I do.

As a value added, the good folks at OakTree put on workshops for users, where oohs and ahs are to be heard emanating from users like me who suddenly realize that Accordance can even do *that*!

Perhaps most remarkably of all, OakTree staff actually answer phone calls and emails, promptly, helpfully, and without making you feel like a techno-maggot.

David Baer

President and CEO, Overseas Council

I have been involved in serious Bible study for nearly 30 years now and have used many different Bible Study software programs. On switching to a Mac in 2001 I was given a copy of Accordance as a gift after speaking at a conference. What a gift! I was amazed at what Accordance was able to do. My friends and I used to discuss what the ultimate Bible software program would do. To my amazement Accordance provided everything we ever longed for and much more that we hadn't thought of.

From that point on Accordance has been my constant companion. I travel extensively and am amazed that as I travel I can carry with me a wealth of translations, commentaries, dictionaries, maps, my own help notes and even an electronic version of my Bible highlights. What would have required many suitcases to carry in the pre computer days is now instantly available to me just by opening my laptop. The personal support, constant upgrades and improvements, and professional service all make Accordance the one Bible software tool no serious Bible scholar should be without. Thank you Oaktree Software.

Bruce Billington

Consultant, Strategic Resource Training

I view Accordance as some view a famous credit card: I "don't leave home without it." It is excellent portable Bible study at a click's notice. Simply wonderful.

Darrell Bock

Research Professor of New Testament Studies, Dallas Theological Seminary, Professor of Spiritual Development and Culture, Center for Christian Leadership

A good friend of mine turned me on to Accordance a few years ago, and I’ve been hooked ever since. The icon is a mainstay on my desktop, as I constantly use the program for research and quick reference. I also incorporate it when teaching to enhance lectures and seminar discussion. Accordance has also saved me hours of library time by providing valuable information that is only a few clicks away.

Theodore Burgh

Associate Professor in the Department of Philosophy and Religion at UNCW

I've used and reviewed all the major players in the Bible software field, and all of them can do amazing things. At the end of the day, however, the program I rely on most for study and teaching is Accordance. With its nimble navigation functions, speedy search capabilities, and impressive collection of tightly integrated resources, Accordance 8 is more than a Bible study resource – it’s like a genie on a hard drive, with no limit on wishes.

Tony Cartledge

Associate Professor of Old Testament at Campbell University Divinity School and Contributing Editor for Baptists Today.

As a student of Scripture for twenty-five years I've continually been searching for the perfect Bible Software. I have never been more pleased than I am with Accordance. I use it not only for preparing talks, but I use it during my live national talk radio show. In a fast paced morning show I need information quickly and efficiently, and Accordance does just that. I also host a live national TV show and I can't tell you the number of times that Accordance has helped me just minutes before going on the air. Thank you for a simple, powerful and intuitive software package.

Jeff Cavins

Director of the Archbishop Harry J. Flynn Catechetical Institute, St. Paul, Minnesota.

Accordance is a great Bible program - one I always talk about. I've taught several college courses on hermeneutics and have always plugged Accordance as the "must have" Bible program. Its commitment to the accuracy of original texts, the commentaries and other resources are plentiful. Besides, this program is the best at being "user-friendly." In my personal Bible study, aside from wanting to touch a paper page occasionally, Accordance is the program I use for sermon and classroom teaching preparation. I cannot say enough good things about this program.

Raymond C. Ciervo

Ray Ciervo Ministries

Accordance for the Macintosh is by far the best computer Bible program available today. In addition to searching many Bibles in various languages and tools like Hebrew and Greek dictionaries one can also search individual modules separately (e.g., Qumran Sectarian MSS, Pseudepigrapha, Mishnah in Hebrew or English, or Apostolic Fathers in Greek, Latin, or English), a boon for the serious student and scholar alike. For its user friendliness, for the speed of even complex context searches (most take only a second or two), and for the enormous amount of material that is available (literally) at one’s fingertips, Accordance will simply astound even a jaded computer buff. A splendid program that keeps getting better and better and easier to use.

Alexander A. Di Lella, O.F.M

Professor Emeritus of Biblical Studies, The Catholic University of America

I have used Accordance software for ten years and will keep on using it as long as I pursue biblical studies. I have used other Bible software and none of it compares to the power, efficiency, and ease of Accordance. I recommend it enthusiastically.

Craig A. Evans

Payzant Distinguished Professor of New Testament, Acadia Divinity College, author of Mark in the Word Biblical Commentary

I like to have the very best in conjunction with the very best. For computers this is Macintosh and for programs this is Accordance. Accordance is the most user-friendly program that has the most texts and tools I am interested in. Of course you have to learn the program, but once you know the major principles everything else becomes very easy. I like Accordance for my own work and for my students. The major area of my interest is that of the philological and textual study of the Hebrew and Greek Bible. For my own work in this area I now use Accordance more than printed books. With a wide screen I can see several sources at the same time. I print out some results, although I always have one of my laptops with me in my courses. I am amazed at the quality of Accordance and at the beautiful results I get for very sophisticated search questions. The excellent dictionaries of Accordance help me to get to all the required words, phrases, and combinations. The graphs, analyses, and concordances are absolutely fabulous.

I enjoy exploring the various aspects of the Hebrew text of the Bible, alone, and in conjunction with its various ancient translations, and now also with the Samaritan Pentateuch, and soon with the Biblical Qumran scrolls. All these can be shown in parallel windows, and in the case of the Hebrew and Greek Bible, with every version of Accordance the comparison is more sophisticated and user-friendly. I also enjoy the wealth of ancient sources around the Bible. Three years ago, I founded at the Hebrew University a computer course within the Dept of Bible that is based on Accordance. That program is now installed in the library and at the server of the Computer Instruction unit on Mt Scopus, so that students can actively use the program.

I am happy with Accordance, and I am proud of it.

Prof. Emanuel Tov

J. L. Magnes Professor of Bible, Hebrew University, Jerusalem

Mac people think differently than PC people. The Mac user requires a software work environment that is intensely intuitive. And the Accordance software is the most intuitive that I know. As smooth as silk, one can set up a passage or a word search, and move effortlessly through the myriad of illuminating tools that Accordance proffers. I have never used an owner's manual, written instructions, or Accordance tutorial ... but I always can find what I want! Amazing!

George Joseph Gatgounis, Esq

Attorney and Consultant at Law

In the 1980’s I began teaching in Seminary and realized that I needed to invest in a computer to further my work. However, the computers available at that time did not particularly interest me. Then Apple unveiled their Super Bowl 1984 Macintosh ad. I was hooked. This was a real computer! I purchased a 128K Mac – all the memory that I would ever need!

Before too long, I learned how to get the Hebrew Scriptures on disc, paste text into handouts for class and create overhead transparencies. I tried all kinds of Bible software, on various platforms, and finally found “acCordance” for the Mac with The GRAMCORD Institute in 1994. Computer Bible study with Accordance became an essential supplement to my study and teaching. Through the years this progressed to better handouts and computer projected presentations. Beginning in 2004, with the maturing of Accordance, Hebrew/Greek/English computer Bible study moved more and more to the center of my study and teaching. Today Accordance is both central and essential.

I am delighted with the ever-expanding capabilities that the people at OakTree Software have brought to Accordance and highly recommend it to my students, colleagues, and all students of the Bible. The staff has always been extremely helpful in assisting me with purchases, especially given my nontraditional route into the modules. I appreciate the fact that students can begin their journey with a more modest investment and then add modules as they have resources. The many training tools further enhance Accordance’s already user friendly interface – David Lang’s Training DVDs, Tim Jenney’s podcasts, written documentation, revised Help screens, User Forums, and Training Seminars (I recently attended my first). And now it is so easy to pop pictures and charts into projected presentations as well as to project Accordance itself for classes and churches.

Today, my laptop (or iPhone or iPad) with Accordance goes with me wherever I go, both for my own reading and study and for teaching. My electronic library is with me whether I am teaching at my own Seminary in the US or teaching overseas. As I have traveled in other ministries, it has been great to have so much so conveniently at my fingertips wherever I am. I look forward to many more exciting developments and capabilities in the years to come! To paraphrase someone else in another context, I started out looking for a Piper Cub and what I have found in Accordance is a 747!

David B. Kennedy

Associate Professor of Old Testament, Grand Rapids Theological Seminary

Accordance is, simply put, the very best piece of software in its class. It makes my research and writing significantly easier. 

When it comes to research, it is hard to know where to begin the praise. The search can be simple and it can be powerful, straightforward and never really complex. I have yet to find anything for which I cannot search. In doing statistical work for Basics of Biblical Greek, not only for words but for longer phrases and grammatical constructions, Accordance has always been able to give me the right numbers. The databases are accurate and trustworthy, not giving me false positives.

Cosmetically, I can arrange the windows any way I want. I can keep texts in sync. With zones I can now keep my main text before me and do my searching in other synced windows. I can put commentaries and study notes within easy access without crowding out the biblical texts. It is like Accordance was thinking of me when they built such a flexible interface.

In terms of research, I continue to be amazed at the depth of their reference books. They have almost every reference book and commentary series I use. And they are aggressive at continuing to get more. If you buy into their system, you wouldn't be disappointed down the road. This is especially true if you are in Old Testament studies; the depth of their esoteric references is mind boggling.

As I have worked on the translation committees for both the ESV and the NIV, I have found Accordance essential. They have all the translations, many of the original texts (including papyri), all presented in such a way that it makes translation much easier. If you like either of those translations, you can thank Accordance.

And finally, technical support is excellent. As always, please read the manuals, but if you still have questions you can get help. The new Web site is especially helpful, giving you quick access to your purchases with nearly automatic downloads.

Thanks Accordance.

William D. Mounce

Former Professor of New Testament, Gordon-Conwell Theological Seminary Author of The Basics of Biblical Greek and other books

Throughout the writing of my chapters for the new atlas, The Sacred Bridge, Carta's Altas of the Biblical World, I made constant use of the Accordance Program. The need to cite many passages from the Hebrew Bible, the Greek Septuagint and other sources (including the Targums) was made easy by using Accordance (then version 6). The use of several columns in a Search Window let me see the Hebrew, the Greek and some times certain English translations all in a glance. Countless hours were saved by the quick search capacity of Accordance.

Some of the reference tools were also found indispensable. The outlines and bibliographies of articles in the Anchor Bible Dictionary were a great help and saved me the need to spend hours in libraries.

My partner in this project, R. Steven Notley, also made similar and constant use of Accordance for his chapters in New Testament and Second Temple historical geography.

Now, with Version 7, I look forward to many happy hours of productive writing during which I will have the powerful resources of Accordance at my fingertips.

It is also a pleasant opportunity to express my appreciation for all the expert staff members. They have always supported me with the highest of professional support accompanied with a cordial and cheerful attitude. The are genuine servants of our academic community.

After years of working with [other software], Accordance quickly advanced to be my workhorse. The simple and intuitive interface kept the learning curve short. Working with original language texts is so easy that even beginners will find Accordance helpful. The layout of the construct searches is intuitive and automated. However, this simplicity is a little devious. The possibilities of creating complex searches are so far reaching that they can hardly be exhausted. Especially attractive are the possibilities of creating searches for whole groups of texts. Finally, Accordance is very speedy. Nevertheless, the decision for Accordance entails a substantial financial investment. For this one gets the best bible program on the market today.

Right from the start it can be said that Accordance Bible Software impressively combines elegance with speed...

After playing with Accordance for a few months, the verdict is in. It’s sweet. If you need a good -- no -- great Bible study aid, ain’t nothing going to touch this. It’s that good. While it has its share of deficiencies, they are minor and heavily overshadowed by the brilliance of the rest of the program. As we state in the review, it may be reason enough to turn PC users into switchers for sure! Take a look at the review and then take a look at OakTree’s site. You’ll be amazed at the power you’ve been missing in God’s Word!

I’ve been working for Accordance for more than two decades now, and in that time, I’ve done a little bit of everything (except the actual programming!): module development, interface design, help design, blogging, training, video tutorials, etc. As the company has grown, we’ve brought in smarter and better-qualified people to do most of those tasks, and I’m now primarily responsible for quality control and creative projects like the Bible Times PhotoMuseum. You would think that after twenty-plus years I’d be a little jaded, but I feel so blessed to do what I do for a living, to work with people whom I genuinely love and admire, and to serve customers who are passionate about studying and teaching the Bible. It has been a dream job, and I’m excited to see what the next two decades have in store!

I'm the head of software development at Accordance, and I really love the development process. Taking ideas, implementing them, working with our users, and then releasing a new feature for Accordance is an amazing experience. I am regularly humbled by the exciting work our users accomplish with Accordance, ranging from user's devotions, to teacher's handouts and lectures, to published academic papers. It has been over a decade since I started my work for Accordance, and I cannot wait to see what the future has in store. When not working for Accordance, I play trombone professionally in the Orlando Philharmonic Orchestra and teach at my local congregation.

I started working for Accordance in February of 2009. I was a stay-at-home mom of three for 15 years, prior to coming to work at Accordance. The company was nothing but supportive in my transition and has always gone above and beyond what any employer would have done. I feel very blessed to be employed here and to be able to come to work each and every day doing what I do. I truly love our customers, my colleagues, our product and what it enables people to do, and the feeling that I am a part of it in some way. Accordance is my home away from home.

Christopher Rockwell

I am a Texas native, more specifically Northeast Texas. For those wondering, yes I grew up with cows in my backyard, which is not as common as you think where I am from. I’ve always been intrigued with computers and technology as a whole, even as a youngster, but wasn’t exposed to programming until my freshman year in college at Prairie View A&M. At the time, I was majoring in Computer and Electrical Engineering, but that soon changed after watching the movie The Social Network. That movie, which chronicles the start of Facebook, captivated me and exposed me to something I had never known nor heard of before, coding. From that day forward I have been engulfed in my passion for programming and went on to attend Full Sail University, where I graduated, Salutatorian, with a Bachelors in Mobile Development. I was super excited when I received the lead from my college for the job opening at Accordance. A job that combines two things I love, my faith and programming. I have grown and learned so much as a programmer and as a person since I joined the team back in 2015 and I am looking forward to what the future has in store.

Music, photography, travel and healthy living are some of my personal interests.

I have worked for Accordance part-time since November 2012 although I have been using the software since 1999. Although I typically work from home I enjoy my colleagues with Accordance very much and have great respect for the management team. I am the assistant to the CFO and enjoy organizing information, crunching numbers, and working on the payment plans and royalties. I so appreciate supporting a company that provides the Word of God and assorted modules to others to enable them to teach, learn and study the Bible accurately.
