2 Kings 16:2-4

²Ahaz was twenty years old when he became king, and he reigned for 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. ³But he walked in the way of the kings of Israel, and he even made his son pass through the fire, in accordance with the abominations of the nations whom the Lord had driven out before the sons of Israel. ⁴And he sacrificed and burned incense on the high places, on the hills, and under every green tree.
