2 Chronicles 28:2-4

²but he walked in the ways of the kings of Israel, and made also molten images for the Baals. ³Moreover he burnt incense in the valley of the son of Hinnom, and burnt his children in the fire, according to the abominations of the nations whom Yahweh cast out before the children of Israel. ⁴He sacrificed and burnt incense in the high places, and on the hills, and under every green tree.
