2 Chronicles 33:11-16

Wherefore Jehovah brought upon them the captains of the host of the king of Assyria, who took Manasseh in chains, and bound him with fetters, and carried him to Babylon. And when he was in distress, he besought Jehovah his God, and humbled himself greatly before the God of his fathers. And he prayed unto him; and he was entreated of him, and heard his supplication, and brought him again to Jerusalem into his kingdom. Then Manasseh knew that Jehovah he was God. Now after this he built an outer wall to the city of David, on the west side of Gihon, in the valley, even to the entrance at the fish gate; and he compassed Ophel about with it, and raised it up to a very great height: and he put valiant captains in all the fortified cities of Judah. And he took away the foreign gods, and the idol out of the house of Jehovah, and all the altars that he had built in the mount of the house of Jehovah, and in Jerusalem, and cast them out of the city. And he built up the altar of Jehovah, and offered thereon sacrifices of peace-offerings and of thanksgiving, and commanded Judah to serve Jehovah, the God of Israel.
