2 Chronicles 33:14-16

14After this he built a wall outside the City of David on the west side of Gihon, in the valley, as far as the entrance of the Fish Gate; and it enclosed Ophel, and he raised it to a very great height. Then he put military captains in all the fortified cities of Judah.

15He took away the foreign gods and the idol from the house of the Lord, and all the altars that he had built in the mount of the house of the Lord and in Jerusalem; and he cast them out of the city.

16He also repaired the altar of the Lord, sacrificed peace offerings and thank offerings on it, and commanded Judah to serve the Lord God of Israel.
