2 Kings 21:3, 6

For he rebuilt the high places that Hezekiah his father had destroyed, and he erected altars for Baal and made an Asherah, as Ahab king of Israel had done, and worshiped all the host of heaven and served them.

And he burned his son as an offering and used fortune-telling and omens and dealt with mediums and with necromancers. He did much evil in the sight of the LORD, provoking him to anger.
