II Kings 21:3, 6

For he rebuilt the high places which Hezekiah his father had destroyed; he raised up altars for Baal, and made a wooden image, as Ahab king of Israel had done; and he worshiped all the host of heaven and served them.

Also he made his son pass through the fire, practiced soothsaying, used witchcraft, and consulted spiritists and mediums. He did much evil in the sight of the LORD, to provoke Him to anger.
