are what Accordance calls the numbering systems used to identify the original Hebrew or Greek words behind the English text. Strong's is the original and best known system, but the Zondervan materials use the Goodrick-Kohlenberger numbers. Accordance makes it really easy to see the numbers, look them up in the dictionary, search on them and analyse them.
So many people just use the Key numbers to look up the dictionary article on a word. Our latest chapter in the Beginning in Mark
series, Keys to the Original
, shows you how to go much further in exploring the original words that lie behind the English text.
