2 Chronicles 33:15-17

15And he removed the strange 1gods, and the idol out of the house of Jehovah, and all the altars that he had built on the mount of the house of Jehovah and in Jerusalem, and cast [them] out of the city.

16And he reinstated the altar of Jehovah, and sacrificed on it peace-offerings and thank-offerings, and commanded Judah to serve Jehovah the 2God of Israel.

17Nevertheless, the people sacrificed still on the high places, although to Jehovah their 3God only.
