2 Chronicles 33:14-18

Now after this he built the outer wall of the city of David on the west side of Gihon, in the valley, up to the entrance of the Fish Gate; and he encircled the Ophel with it and made it very high. Then he put army commanders in all the fortified cities in Judah.

He also removed the foreign gods and the idol from the house of the Lord, as well as all the altars which he had built on the mountain of the house of the Lord and in Jerusalem, and he threw them outside the city.

He set up the altar of the Lord and sacrificed peace offerings and thanksgiving offerings on it; and he ordered Judah to serve the Lord God of Israel.

However, the people still sacrificed on the high places, although only to the Lord their God.

Now the rest of the acts of Manasseh and his prayer to his God, and the words of the seers who spoke to him in the name of the Lord God of Israel, behold, they are among the records of the kings of Israel.
