1 Kings 16:30-33

And Ahab the son of Omri did evil in the sight of the LORD above all that were before him. And it came to pass, as if it had been a light thing for him to walk in the sins of Jeroboam the son of Nebat, that he took to wife Jezebel the daughter of Ethbaal king of the Zidonians, and went and served Baal, and worshipped him. And he reared up an altar for Baal in the house of Baal, which he had built in Samaria. And Ahab made a grove; and Ahab did more to provoke the LORD God of Israel to anger than all the kings of Israel that were before him.
