II Chronicles 33:10-13

And the LORD spoke to Manasseh and his people, but they would not listen. Therefore the LORD brought upon them the captains of the army of the king of Assyria, who took Manasseh with hooks, bound him with bronze fetters, and carried him off to Babylon. Now when he was in affliction, he implored the LORD his God, and humbled himself greatly before the God of his fathers, and prayed to Him; and He received his entreaty, heard his supplication, and brought him back to Jerusalem into his kingdom. Then Manasseh knew that the LORD was God.
