31 And Jehoram, the son of Ahab, became king over Israel in Samaria in the eighteenth year of the rule of Jehoshaphat, king of Judah; and he was king for twelve years. 2 He did evil in the eyes of the Lord; but not like his father and his mother, for he put away the stone pillar of Baal which his father had made. 3 But still he did the same sins which Jeroboam, the son of Nebat, did and made Israel do; he went on in 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.
