2 Chronicles 19:1

And Jehoshaphat. Chapter 19 contains materials not appearing in the record of Kings. It includes such items as the prophetic rebuke of Jehoshaphat after his return from Ramoth-gilead (vs. 1-3), the king’s personal efforts at religious reformation (v. 4), and his reform of the judicial system (vs. 5-11).

Returned. Ahab and Jehoshaphat had been unsuccessful in their efforts to retake Ramoth-gilead. The troops returned to their homes, and the enterprise was presumably abandoned (see 1 Kings 22:36). The record implies that the Syrians had successfully repulsed the attack, but had made no attempt to follow up their success. Jehoshaphat returned to Jerusalem sound and unhurt, a sadder but wiser man.
