What were the evils of King Ahab and his wife Jezebel? What steps did God take to deal with them?
Sounds to me like someone is looking for a shortcut to getting his Bible lesson done. A summary is given in I Kings 16:30-34. "Now Ahab the son of Omri did evil in the sight of the LORD, more than all who were before him. And it came to pass, as though it had been a trivial thing for him to walk in the sins of Jeroboam the son of Nebat, that he took as wife Jezebel the daughter of Ethbaal, king of the Sidonians; and he went and served Baal and worshiped him. Then he set up an altar for Baal in the temple of Baal, which he had built in Samaria. And Ahab made a wooden image. Ahab did more to provoke the LORD God of Israel to anger than all the kings of Israel who were before him. In his days Hiel of Bethel built Jericho. He laid its foundation with Abiram his firstborn, and with his youngest son Segub he set up its gates, according to the word of the LORD, which He had spoken through Joshua the son of Nun" (I Kings 16:30-34). These are not all of Ahab or Jezebel's sins, but they do tell you what type a people they were.
Ahab's reign is discussed in I Kings 16:29-22:40 and II Chronicles 18:1-34.
