2 Chronicles 28:2-4

21But he walked in the ways of the kings of Israel; he also 2made cast metal images for the Baals. 3Furthermore, 3he burned incense in the Valley of Ben-hinnom, and 4burned his sons in fire, 5according to the abominations of the nations whom the Lord had driven out from the sons of Israel. 4He sacrificed and 6burned incense on the high places, on the hills, and under every green tree.
