I visited the Christian bookstore today to see what's new. (The Christian bookstore near my job actually carries books. What a concept!)
Have you ever wondered what a Bible word meant in the original language, but didn't know how to look it up because you don't know Greek or Hebrew? Well, here is a great solution:
Mounce's Complete Expository Dictionary of Old & New Testament Words
If you have ever heard of Vine's, this is meant to replace that. I've always been hesitant about recommending Vine's because even though it's lay-friendly, the definitions are rather dated.
What's super cool about Mounce's dictionary is that you look the words up in English and then it gives the discussion about the Hebrew and Greek terms (whereas Vine's separates the Hebrew and Greek definitions). Other expository dictionaries (like Theological Wordbook of the Old Testament) are more academic. So they alphabatize the words in Greek and Hebrew, which makes it a little difficult to look stuff up when you don't know the original languages.
So, if you're looking for a good lay-person's dictionary of Bible words, this is it!
