For big picture overview and some helpful background information, we would recommend the chapter on 1-2 Kings in A Biblical-Theological Introduction to the Old Testament: The Gospel Promised. Peter Leithart’s commentary on 1-2 Kings in the Brazos Theological Commentary series is very insightful, and was the resource Nate was using for much of the typology discussion. For a more application driven book, we would highly recommend Dale Ralph Davis’ 2 Kings: The Power and The Fury. As always, if you prefer to visualize things will find The Bible Project videos on 1-2 Kings useful: https://youtu.be/bVFW3wbi9pk
