At once, Omri and his army marched to Tirzah and attacked.
When Zimri saw that the town was captured, he ran into the strongest part of the palace and killed himself by setting it on fire.
He and his troops fought in Shechem all day, until they had killed everyone in town. Then he and his men tore down the houses and buildings and scattered salt everywhere.
After destroying Shechem, Abimelech went to Thebez. He surrounded the town and captured it.
