King Jehoshaphat (Hebrew, "YHWH judges") (949-r. 914-889 BC according to Ussher, or 907-r. 872-848 BC according to Thiele) was the fourth king of the Southern Kingdom since the division of the kingdoms of Israel. Although his name has become a modern proverb ("Jumping Jehoshaphat"), he is one of the least-appreciated of the Southern Kingdom's "right-doing" kings. However, he would mar his reputation as a reformer by entering into three supremely ill-advised alliances, one of which included what would prove one of the most disastrous marriages in the history of the House of David.
