II Chronicles 33:12, 19, 23

Now when he was in affliction, he implored the LORD his God, and humbled himself greatly before the God of his fathers

Also his prayer and how God received his entreaty, and all his sin and trespass, and the sites where he built high places and set up wooden images and carved images, before he was humbled, indeed they are written among the sayings of Hozai.

And he did not humble himself before the LORD, as his father Manasseh had humbled himself; but Amon trespassed more and more.
