2 Chronicles 33:21-25 New King James Version (NKJV)
Amon’s Reign and Death
21 Amon was twenty-two years old when he became king, and he reigned two years in Jerusalem. 22 But he did evil in the sight of the Lord, as his father Manasseh had done; for Amon sacrificed to all the carved images which his father Manasseh had made, and served them. 23 And he did not humble himself before the Lord, as his father Manasseh had humbled himself; but Amon trespassed more and more.
24 Then his servants conspired against him, and killed him in his own house. 25 But the people of the land executed all those who had conspired against King Amon. Then the people of the land made his son Josiah king in his place.
2 Chronicles 33:21-25 New International Version (NIV)
Amon King of Judah
21 Amon was twenty-two years old when he became king, and he reigned in Jerusalem two years. 22 He did evil in the eyes of the Lord, as his father Manasseh had done. Amon worshiped and offered sacrifices to all the idols Manasseh had made. 23 But unlike his father Manasseh, he did not humble himself before the Lord; Amon increased his guilt.
24 Amon’s officials conspired against him and assassinated him in his palace. 25 Then the people of the land killed all who had plotted against King Amon, and they made Josiah his son king in his place.
