“Amon was twenty and two years old when he began to reign, and he reigned two years in Jerusalem. And his mother's name was Meshullemeth, the daughter of Haruz of Jotbah.”
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.
“And he removed from thence unto a mountain on the east of Bethel, and pitched his tent, having Bethel on the west, and Hai on the east: and there he builded an altar unto the LORD, and called upon the name of the LORD.”
