II Kings 16:1-5

In the seventeenth year of Pekah the son of Remaliah, Ahaz the son of Jotham, king of Judah, began to reign. Ahaz was twenty years old when he became king, and he reigned sixteen years in Jerusalem; and he did not do what was right in the sight of the LORD his God, as his father David had done. But he walked in the way of the kings of Israel; indeed he made his son pass through the fire, according to the abominations of the nations whom the LORD had cast out from before the children of Israel. And he sacrificed and burned incense on the high places, on the hills, and under every green tree. Then Rezin king of Syria and Pekah the son of Remaliah, king of Israel, came up to Jerusalem to make war; and they besieged Ahaz but could not overcome him.
