Charles Ellicott Commentary 2 Chronicles 22:3

"He also walked in the ways of the house of Ahab; for his mother was his counsellor to do wickedly." — 2 Chronicles 22:3 (ASV)

He also.—The pronoun is emphatic: he too, like his father. Kings: And he walked.

Walked in the ways of the house of Ahab.—2 Chronicles 21:6; 2 Chronicles 21:13; Micah 6:16.

For his mother was his counsellor to do wickedly.—Not in Kings; an explanatory remark added by the chronicler. (Compare 2 Chronicles 20:35; 2 Chronicles 21:6.) Her influence would be used in support of the Baal worship, which was the symbol of alliance with the northern kingdom.
