Charles Ellicott Commentary 2 Chronicles 33:15

"And he took away the foreign gods, and the idol out of the house of Jehovah, and all the altars that he had built in the mount of the house of Jehovah, and in Jerusalem, and cast them out of the city." — 2 Chronicles 33:15 (ASV)

Took away the strange gods. —Compare 2 Chronicles 33:3–7. For the phrase “strange gods” (ĕlôhê nçkâr), see Genesis 35:2.

The idol. —That is, the Asherah (2 Chronicles 33:3; 2 Chronicles 33:7; 2 Kings 21:7; 2 Kings 17:16).

In the mount of the house. —The temple hill. Thenius says: the courts with the altars in them (2 Kings 21:4–5).

Cast them out. —Compare 2 Chronicles 29:16; 2 Chronicles 30:14. Manasseh’s reform was hardly complete, for some of his altars remained for Josiah to pull down (2 Kings 23:12).
