2 Kings 16:2-4

Amplified Bible

² Ahaz was twenty years old when he became king, and he reigned sixteen years in Jerusalem. He did not do what was right in the sight of the Lord his God, as his father (ancestor) David had done. ³ Instead he walked in the way of the [idolatrous] kings of Israel, and even made his son pass through the fire [as a human sacrifice], in accordance with the repulsive [and idolatrous] practices of the [pagan] nations whom the Lord drove out before the Israelites. ⁴ He also sacrificed and burned incense on the high places and on the hills and under every green tree.
