19 Amon was twenty-two years old when he began to reign, and he reigned two years in Jerusalem. His mother's name was Meshullemeth the daughter of Haruz of Jotbah. 20 And he did what was evil in the sight of the Lord, as Manasseh his father had done. 21 He walked in all the way in which his father walked and served the idols that his father served and worshiped them. 22 He abandoned the Lord, the God of his fathers, and did not walk in the way of the Lord.
Matthew Henry's Commentary on 2 Kings 21:19-22
Commentary on 2 Kings 21:19-26
(Read 2 Kings 21:19-26)
Amon profaned God's house with his idols; and God suffered his house to be polluted with his blood. How unrighteous soever they were that did it, God was righteous who suffered it to be done. Now was a happy change from one of the worst, to one of the best of the kings of Judah. Once more Judah was tried with a reformation. Whether the Lord bears long with presumptuous offenders, or speedily cuts them off in their sins, all must perish who persist in refusing to walk in his ways.
