The Dividing Wall of Hostility
A while back, I was reading through Ephesians with my family, and we stumbled across the phrase, "the dividing wall of hostility." To explain what this means, and to show that Paul was not just being metaphorical, I opened the Bible Lands PhotoGuide. The first thing I did was to go to the Temple Mount subarticle of the Jerusalem article and show a reconstruction of the Herodian temple.
Using this image, I was able to show my wife and kids the various temple courts, explaining that Gentiles were only permitted in the outer court of the Gentiles, that Jewish men and women were permitted in the Court of the Women, and that only Jewish men were permitted inside the Court of the Men. I then turned to the Inscriptions article and showed the Greek temple inscription which warned Gentiles not to enter.
This inscription contains the ominous words, "Whoever is captured will have himself to blame for his subsequent death."
Showing these images really helped to make real what Paul was referring to when he spoke of the "dividing wall of hostility" between Jews and Gentiles.
It later occurred to me that there might also be some useful diagrams of the temple complex in the Holman Book of Biblical Charts, Maps, and Reconstructions. Doing a quick search for the word "temple" in that module led me to a useful floorplan of the temple complete with indications of where those inscriptions were located.
Now, I happened to be familiar enough with the PhotoGuide to know which images I was looking for and which articles contained them, but had I not, I could easily have found the inscription by selecting either the verse reference for Ephesians 2:14 or the words "dividing wall" and amplifying to the PhotoGuide. I then could have selected the word "temple" in the PhotoGuide and clicked the search button on the Resource palette to find the images of the Temple mount.
The PhotoGuide is a tremendous resource for information about the historical and geographical background behind the text of the Bible. If you have it, be sure to search it for the verses you happen to be studying. You may very well find that a picture from the PhotoGuide is worth a thousand words of commentary.
