This visit indicates an entire change in the relations which we have hitherto found subsisting between the kingdoms of Israel and Judah. The common danger to which the two kingdoms were exposed from the growing power of Syria had probably induced them to forget their differences. Jehoshaphat’s eldest son, Jehoram, was married to Athaliah, the daughter of Ahab: but apparently the bond between the two families had not hitherto led to any very close intimacy, much less to any joint military expeditions. Jehoshaphat seems to have taken no part in the former Syrian wars of Ahab, nor did he join in the great league against the Assyrians (1 Kings 22:1 note). His visit now was probably one of mere friendliness, without any political object. Ahab, however, turned the visit to political advantage. From this time until the displacement of Ahab’s dynasty by Jehu, very intimate relations subsisted between the two kingdoms (1 Kings 22:49; 2 Kings 3:7; 2 Kings 8:28-29; 2 Chronicles 20:36, etc.).
