2 Kings 16:1-5

In the seventeenth year of Pekah the son of Remaliah, Ahaz the son of Jotham, king of Judah, became king. 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, and even made his son pass through the fire, according to the abominations of the nations whom the LORD had driven out from before the sons of Israel. He sacrificed and burned incense on the high places and on the hills and under every green tree. Then Rezin king of Aram and Pekah son of Remaliah, king of Israel, came up to Jerusalem to wage war; and they besieged Ahaz, but could not overcome him.
