Charles Ellicott Commentary 2 Kings 3:2

"And he did that which was evil in the sight of Jehovah, but not like his father, and like his mother; for he put away the pillar of Baal that his father had made." — 2 Kings 3:2 (ASV)

Wrought evil. — He did evil in the eyes, and so on; that is, he maintained the illicit worship of the bullock at Bethel (2 Kings 3:3).

Like his mother. — Jezebel lived throughout his reign (2 Kings 9:30), which explains why he did not eradicate Baal worship (2 Kings 10:18–28).

For he put away. — And he removed, that is, from its place in the temple of Baal (compare to 1 Kings 16:31–32). It must have been restored afterwards, probably by the influence of Jezebel (compare to 2 Kings 10:26–27, and Notes).

The image. — Pillar (compare to 2 Chronicles 34:4). The Septuagint, Vulgate, and Arabic read “pillars” (a different pointing); and the Septuagint adds at the end, “and brake them in pieces.” This seems original. Ahab would likely have set up more than one pillar to Baal.
