2 Chronicles 28:2 (KJV)

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:

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.

For Pekah the son of Remaliah slew in Judah an hundred and twenty thousand in one day, which were all valiant men; because they had forsaken the LORD God of their fathers.

And Zichri, a mighty man of Ephraim, slew Maaseiah the king's son, and Azrikam the governor of the house, and Elkanah that was next to the king.
