II Chronicles 28:2-4

For he walked in the ways of the kings of Israel, and made molded images for the Baals. He burned incense in the Valley of the Son of Hinnom, and burned his children in the fire, according to the abominations of the nations whom the LORD had cast out before the children of Israel. And he sacrificed and burned incense on the high places, on the hills, and under every green tree.
