“And he walked in all the way that his father walked in, and served the idols that his father served, and worshipped them:”
King James Version (KJV)
Matthew Henry's Concise Commentary
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.
“O LORD of hosts, God of Israel, that dwellest between the cherubims, thou art the God, even thou alone, of all the kingdoms of the earth: thou hast made heaven and earth.”
