Jehuty X,
Another thing to add, not all concordances are the same.
The Textual Concordance of Holy Scripture that was list above is divided up into topics. The moral section is the largest. If you want to find all the verses dealing with marriage you would look up marriage. If you want to find verses dealing with confession you would look that up.
The Strong’s Concordance that was mentioned earlier is different from the Textual. There are different versions of the Strongs for one thing. The one I have is a
Greek/Hebrew Concordance. It has all the words in the Bible and what they are in the Hebrew Old Testament and the Greek New Testament. Unfortunately the Strong’s is based on the abridged version of the KJV. The one that is missing the 7 Deuterocanonical books.
Personally I have found the Strong’s to be of more value than the Textual. I’m interested in the RSV-CE Concordance but I would need to know more about it. The description doesn’t really say a whole lot. It also doesn’t tell you how much it is.
