2 Kings 21:19-23

19Amon was twenty-two years old when he began to reign; and he reigned two years in Jerusalem; and his mother's name was Meshullemeth, daughter of Haruz of Jotbah.

20And he did evil in the sight of Jehovah, as Manasseh his father had done;

21and he walked in all the way that his father had walked in, and served the idols that his father had served, and worshipped them;

22and he forsook Jehovah the 1God of his fathers, and walked not in the way of Jehovah.

23And the servants of Amon conspired against him, and slew the king in his own house.
