Amon was the son of Manasseh and fourteenth king of Judah. He was twenty two years old when he ascended the throne and though his reign lasted only two years, they were not pleasant. The few reforms that his father had undertaken toward the last few years of his life were totally undone by him.
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. But unlike his father Manasseh, he did not humble himself before the LORD ; Amon increased his guilt.
(2 Chronicles 33:22-23)
If Amon had any thoughts of repenting as his father had done, his plans were cut short when his own servants conspired against him and assassinated him. His son Josiah succeeded him to the throne.
