John Gill's Bible Commentary Ver. 2. And he wrought evil in the sight of the Lord , etc.] Was guilty of idolatry: but not like his father, and like his mother ; his father Ahab, and his mother Jezebel: for he put away the image of Baal that his father had made ; he did not destroy it, only removed it from the temple of Baal where it was set, that it might not be worshipped, at least publicly, (see 1 Kings 16:31,32) this he did, either moved to it by his own conscience, observing the sudden deaths of his father and brother, which he might suppose was for their idolatry; or in order to obtain success in his war with Moab he was entering into; or being instigated by Jehoshaphat to do it, or otherwise he might refuse to join him.
Matthew Henry Commentary
Verses 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 repen or reform, who only part with the sins they lose by, but continue to love the sins that they think to gain by.
