1 Kings 16:30-33

And Ahab the son of Omri did evil in the sight of the LORD, more than all who were before him. And as if it had been a light thing for him to walk in the sins of Jeroboam the son of Nebat, he took for his wife Jezebel the daughter of Ethbaal king of the Sidonians, and went and served Baal and worshiped him. He erected an altar for Baal in the house of Baal, which he built in Samaria. And Ahab made an Asherah. Ahab did more to provoke the LORD, the God of Israel, to anger than all the kings of Israel who were before him.
