2 Chronicles 33:1, 12, 19

Manasseh was twelve years old when he became king, and he reigned in Jerusalem fifty-five years.

In his distress he sought the favor of the LORD his God and humbled himself greatly before the God of his ancestors.

His prayer and how God was moved by his entreaty, as well as all his sins and unfaithfulness, and the sites where he built high places and set up Asherah poles and idols before he humbled himself—all these are written in the records of the seers.
