2 Chronicles 28:3
“Moreover he burnt incense in the valley of the son of Hinnom, and burnt his children in the fire, after the abominations of the heathen whom the Lord had cast out before the children of Israel.”
Ahaz was twenty years old when he began to reign, and he reigned sixteen years in Jerusalem: but he did not that which was right in the sight of the Lord, like David his father:
For he walked in the ways of the kings of Israel, and made also molten images for Baalim.
Moreover he burnt incense in the valley of the son of Hinnom, and burnt his children in the fire, after the abominations of the heathen whom the Lord had cast out before the children of Israel.
He sacrificed also and burnt incense in the high places, and on the hills, and under every green tree.
Wherefore the Lord his God delivered him into the hand of the king of Syria; and they smote him, and carried away a great multitude of them captives, and brought them to Damascus. And he was also delivered into the hand of the king of Israel, who smote him with a great slaughter.
