2 Chronicles 33:15-17

He got rid of the foreign gods and removed the image from the temple of the LORD, as well as all the altars he had built on the temple hill and in Jerusalem; and he threw them out of the city. Then he restored the altar of the LORD and sacrificed fellowship offerings and thank offerings on it, and told Judah to serve the LORD, the God of Israel. The people, however, continued to sacrifice at the high places, but only to the LORD their God.
