"Among those whose life experience had been shaped beyond recall by the fatal apostasy of Manasseh, was his own son, who came to the throne at the age of twenty-two..Of King Amon it is written: "He walked in all the way that his father walked in, and served the idols that his father served, and worshiped them: and he forsook the Lord God of his fathers" (2 Kings 21:21, 22); he "humbled not himself before the Lord, as Manasseh his father had humbled himself; but Amon trespassed more and more."
