1In the seventeenth year of Pekah the son of Remaliah, Ahaz the son of Jotham, king of Judah, became king. 2Ahaz 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 YHVH his God, as his father David had done. 3But 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 YHVH had driven out from before the sons of Israel. 4He sacrificed and burned incense on the high places and on the hills and under every green tree.
2 Kings 16:1-4
1Ahaz was twenty years old when he became king, and he reigned sixteen years in Jerusalem; and he did not do right in the sight of YHVH as David his father had done. 2But he walked in the ways of the kings of Israel; he also made molten images for the Baals. 3Moreover, he burned incense in the valley of Ben-hinnom and burned his sons in fire, according to the abominations of the nations whom YHVH had driven out before the sons of Israel. 4He sacrificed and burned incense on the high places, on the hills and under every green tree.
