Our best-selling "small" commentary set for laypeople is The Bible Knowledge Commentary duo, edited by John Walvoord and Roy Zuck. (We call it "small" because it's just one volume on the Old Testament and one on the New---but in every other way this set is BIG!) Each Bible book is introduced and outlined, then clearly and reliably explained, passage by passage. Maps, charts, and diagrams will expand and enrich your understanding. Based on the NIV. 2580 pages total, two hardcovers, Victor.
