The International Standard Bible Encyclopedia is on sale now at Christian Book Distributors. Click on this link to see the order page.
ISBE is the encyclopedia I have mentioned recently and I would encourage you to add it to your libraries. It will give you great insight into many of the personalities we have studied in the Bible. There are lengthy articles about the various Bible cities as well.
Sometimes, CBD sells this even cheaper, like in the $50 range. But at $79.99 it is still cheaper than what you will find at Amazon at $129. You can find it at ebay for about $115 unless you buy a really old damaged set.
I think you will be very pleased by having this in your library. It will serve you for many years to come.There are 4 volumes with reasonably sized print. If you want to see my copies just ask.
It’s important to have a tool that will bring together historical and scientific material from outside the Scriptures. The authors and editors have done a fine job of bringing all that material together.
Let me know if you have questions.
