Jehoshaphat’s relation with the northern kingdom was not entered into with a view to weakening the southern kingdom. The king of Judah probably wanted to share some of the prosperity of his kingdom with Ahab. Jehoshaphat’s reign extended over a period of twenty five years. His peaceful overtures toward the northern kingdom probably came during the first half of his reign. The “affinity” with Ahab was effected in the marriage of Jehoshaphat’s son, Jehoram, with Athaliah, daughter of Ahab.
