2 Kings 16:2-4
16:2 Ahaz was twenty years old when he began to reign, and he reigned for sixteen years in Jerusalem. He did not do what pleased the Lord his God, in contrast to his ancestor David.
16:3 He followed in the footsteps of the kings of Israel. He passed his son through the fire, a horrible sin practiced by the nations whom the Lord drove out from before the Israelites.
16:4 He offered sacrifices and burned incense on the high places, on the hills, and under every green tree.
