1 Kings 16:30-33

More than any king before him, Ahab son of Omri did many things the LORD said were wrong. He sinned in the same ways as Jeroboam son of Nebat, but he did even worse things. He married Jezebel daughter of Ethbaal, the king of Sidon. Then Ahab began to serve Baal and worship him. He built a temple in Samaria for worshiping Baal and put an altar there for Baal. Ahab also made an idol for worshiping Asherah. He did more things to make the LORD, the God of Israel, angry than all the other kings before him.
