2 Chronicles 33:14-17

14And after this he built the outer wall of the city of David, on the west, toward Gihon, in the valley, even to the entrance of the fish-gate, and carried it round Ophel, and raised it up a very great height; and he put captains of war in all the fortified cities of Judah.

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.
