This account expands and alters 1 Kings 22:1-59, where the king’s role is less highlighted. The Chronicler develops Jehoshaphat’s character through four alternating scenes: religious and military reform (17), battle and victory (18), judicial reform (19), and a new triumph (20). The military efforts build on those of his father, Asa. Religious reform prepares the way for judicial reform, emphasizing obedience to Deuteronomy and heeding prophets’ warnings about judges (Dt 1:16ff). The military campaigns include one in Chapter 18, which aligns with 1 Kings 22, and another in Chapter 20, an addition by the author. The conclusion of Jehoshaphat’s reign (20:31-21:1) is based on 1 Kings 22:41-51, where his failure is connected to his alliance with the king of Israel.
