31 Now Jehoram the son of Ahab began to reign over Israel in Samaria in the eighteenth year of Jehoshaphat king of Judah, and reigned twelve years. 2 He did that which was evil in the sight of Yahweh, but not like his father, and like his mother; for he put away the pillar of Baal that his father had made. 3 Nevertheless he cleaved to the sins of Jeroboam the son of Nebat, with which he made Israel to sin; he didn’t depart from it.
4 Now Mesha king of Moab was a sheep breeder; and he rendered to the king of Israel the wool of one hundred thousand lambs, and of one hundred thousand rams. 5 But it happened, when Ahab was dead, that the king of Moab rebelled against the king of Israel.

Commentary on 2 Kings 3:1-5
(Read 2 Kings 3:1-5)
Jehoram took warning by God's judgment, and put away the image of Baal, yet he maintained the worship of the calves. Those do not truly repent or reform, who only part with the sins they lose by, but continue to love the sins that they think to gain by.
