2 Chronicles 33:11-13

11Wherefore the Lord brought upon them the captains of the host of the king of Assyria, which took Manasseh among the thorns, and bound him with fetters, and carried him to Babylon.12 12And when he was in affliction, he besought the Lord his God, and humbled himself greatly before the God of his fathers, 13And prayed unto him: and he was intreated of him, and heard his supplication, and brought him again to Jerusalem into his kingdom. Then Manasseh knew that the Lord he was God.
