31 Now Jehoram the son of Ahab became king over Israel at Samaria in the eighteenth year of Jehoshaphat king of Judah, and reigned twelve years. 2 And he did evil in the sight of the Lord, but not like his father and mother; for he put away the sacred pillar of Baal that his father had made. 3 Nevertheless he persisted in the sins of Jeroboam the son of Nebat, who had made Israel sin; he did not depart from them.
Matthew Henry's Commentary on 2 Kings 3:1-3
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.
