1 Kings 16:30-33 NIV

[30] Ahab son of Omri did more evil in the eyes of the LORD than any of those before him. [31] He not only considered it trivial to commit the sins of Jeroboam son of Nebat, but he also married Jezebel daughter of Ethbaal king of the Sidonians, and began to serve Baal and worship him. [32] He set up an altar for Baal in the temple of Baal that he built in Samaria. [33] Ahab also made an Asherah pole and did more to arouse the anger of the LORD, the God of Israel, than did all the kings of Israel before him.
