2 Chronicles 33:15-17

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 thank offerings on it; and he ordered Judah to serve the LORD God of Israel. Nevertheless the people still sacrificed in the high places, although only to the LORD their God.
