2 Chronicles 33:12-19

12And when he was in distress, he besought Jehovah his God, and humbled himself greatly before the God of his fathers. 13And 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.

14Now 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. 15And 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. 16And 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. 17Nevertheless the people sacrificed still in the high places, but only unto Jehovah their God.

18Now the rest of the acts of Manasseh, and his prayer unto his God, and the words of the seers that spake to him in the name of Jehovah, the God of Israel, behold, they are written among the acts of the kings of Israel. 19His prayer also, and how God was entreated of him, and all his sin and his trespass, and the places wherein he built high places, and set up the Asherim and the graven images, before he humbled himself, behold, they are written in the history of Hozai.
