2 Chronicles 33:1, 12, 19

Manasseh was twelve years old when he began to reign, and he reigned fifty-five years in Jerusalem.

And when he was in distress, he entreated the favor of the LORD his God and humbled himself greatly before the God of his fathers.

And his prayer, and how God was moved by his entreaty, and all his sin and his faithlessness, and the sites on which he built high places and set up the Asherim and the images, before he humbled himself, behold, they are written in the Chronicles of the Seers.
