2 Chronicles 33:14-17 King James Version (KJV)
14 Now after this he built a wall without the city of David, on the west side of Gihon, in the valley, even to the entering in at the fish gate, and compassed about Ophel, and raised it up a very great height, and put captains of war in all the fenced cities of Judah.
15 And he took away the strange gods, and the idol out of 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 cast them out of the city.
16 And he repaired the altar of the Lord, and sacrificed thereon peace offerings and thank offerings, and commanded Judah to serve the Lord God of Israel.
17 Nevertheless the people did sacrifice still in the high places, yet unto the Lord their God only.
