1. Kings Zimri and Omri (15-28)
The death of Elah led to civil war in Israel. Some supported Zimri, who proclaimed himself king after killing Elah. Others supported General Omri. Seven days after he became king, he died in a siege. And Omri became king. Omri reigned 12 years, and built up Samaria. He spent it doing evil in the Lord's eyes. He sinned even more than his fathers had done.
2. King Ahab (29-34)
Ahab became king of Israel when his father Omri died. Ahab became the archetype of all the evil kings of Israel. He did more evil than all the other kings before him. He not only thought committing sins was a trivial thing, he also married Jezebel, who led him into the worship of Baal. He set up an Asherah pole, and also rebuilt Jericho, going against the prophesy of Joshua, losing two of his sons in the process. The word of the Lord remained true and faithful.
