I picked up a copy of the "Absolute Beginner's Guide to the Bible" from the local library the other day. All sorts of fascinating little tidbits.
One of the things I found interesting: you're probably familiar with the way the folks of Jesus' day referred to the Old Testament, as "The Law, the Prophets, and the Writings". In Hebrew, the "Law" would be "Torah", the "Prophets" would be "Nevi'im", and the "Writings" would be "Kethuvim". Taking the first letter of each word, you get "T.N.K.", and adding in some vowels, you get "Tanakh". This is the word used by adherents of Judaism to refer to what we call the Old Testament.
