2 Chronicles 33:21-25 - Amon's Reign
21 Amon was 22 years old when he became king, and he reigned two years in Jerusalem. 22 He practiced what the LORD considered to be evil, just as his father Manasseh had done, sacrificing to and serving all the carved images that his father Manasseh had made, 23 except that he never humbled himself to the LORD like his father Manasseh had done. In fact, Amon multiplied his own guilt
24 until his servants finally conspired against him and executed him in his own palace. 25 But the people of the land executed all of the conspirators against King Amon and installed his son Josiah as king to succeed him.
