In my opinion, the finest single commentary on the Old Testament is Unger's Bible Commentary (not to be confused with his far more general Unger's Bible Handbook) has just been reprinted after a lapse of about 30 years! It has recently been reprinted by AMG publishers and is available from www.christianbook.com and even www.amazon.com.
