Charles Ellicott Commentary 1 Kings 22:41

"And Jehoshaphat the son of Asa began to reign over Judah in the fourth year of Ahab king of Israel." — 1 Kings 22:41 (ASV)

Jehoshaphat. — The narrative here, so far as it is full and continuous, centers on the prophetic work of Elijah and Elisha, the scene of which was in Israel. The compiler limits himself to inserting a few brief annalistic notices of the kingdom of Judah, taking up the thread of the narrative of 1 Kings 15:24, except where (as in 2 Kings 3) it becomes connected again with the history of Israel. In the Chronicles, on the contrary, there is a full and interesting account of the reign of Jehoshaphat, and especially of his great religious revival (2 Chronicles 17-20), coinciding with this chapter, almost word for word, in the account of the battle at Ramoth-gilead. The brief notices here of the religious work of Jehoshaphat, his “might,” and his “wars,” agree entirely with this fuller record.
