2 Kings 8:16
Ver. 16. And in the fifth year of Joram the son of Ahab king of Israel,.... Who began his reign in the eighteenth year of Jehoshaphat, 2Ki 3:1.
Jehoshaphat being then king of Judah; as he continued to be two years more; for this must be in the twenty third year of his reign, and he reigned twenty five years, 1Ki 22:42.
Jehoram the son of Jehoshaphat king of Judah began to reign; according to Dr. Lightfoot {h}, there were three beginnings of his reign; "first", when his father went with Ahab to Ramothgilead, when be was left viceroy, and afterwards his father reassumed the kingdom; the "second" time was, when Jehoshaphat went with the kings of Israel and Edom against Moab; and this is the time here respected, which was in the fifth of Joram king of Israel; and the "third" time was, at the death of his father; but knew his father was living.
