ManassehManasseh was twelve years old when he became king, was twelve years old when he became king,

2 Chronicles 33:1-20

Manasseh was twelve years old when he became king, and he reigned in Jerusalem fifty-five years. He did evil in the eyes of the Lord, following the detestable practices of the nations the Lord had driven out before the Israelites. He rebuilt the high places his father Hezekiah had demolished; he also erected altars to the Baals and made Asherah poles. He bowed down to all the starry hosts and worshiped them.

But Manasseh led Judah and the people of Jerusalem astray, so that they did more evil than the nations the Lord had destroyed before the Israelites.
