Numbers

Philip J. Budd, Numbers (WBC)--a compilation of Dr. Budd’s speculation.
Raymond Brown, The Message of Numbers (The Bible Speaks Today)--orthodox but not terribly helpful
John Calvin, Harmony of Exodus, Leviticus, Numbers, Deuteronomy
Gorden J. Wenham, Numbers (TOTC)--a solid, thought provoking, but modern commentary.
