Abimelech, son of Gideon and a concubine from Shechem, persuades his mother's relatives and the people of Shechem to make him their ruler instead of Gideon's seventy sons. They give him seventy pieces of silver from the temple of Baal-berith, with which he hires reckless men. At Ophrah he kills his seventy brothers on one stone. Only Jotham, the youngest, escapes by hiding. The people of Shechem make Abimelech king by the oak of the pillar.
Jotham climbs Mount Gerizim and tells a fable: the trees want a king and ask the olive tree, the fig tree and the vine, but all decline. Only the bramble accepts and warns that, if they do not act in good faith, fire will come out of the bramble and devour the cedars of Lebanon. Jotham applies the fable: if they have acted with integrity toward the house of Gideon, let them rejoice, and if not, let fire come out from Abimelech against Shechem and from Shechem against Abimelech. Jotham flees to Beer.
Three years later God sends a spirit of ill will between Abimelech and Shechem. The Shechemites set ambushes, and Gaal, son of Ebed, arrives and urges them to rebel. Zebul, the city's ruler, warns Abimelech, who attacks at night, defeats Gaal, destroys Shechem and sows it with salt. He burns the tower of Shechem with its thousand inhabitants. Then he attacks Thebez, and as he approaches the tower a woman drops an upper millstone on his head. Abimelech asks his armor-bearer to kill him so that no one will say a woman killed him. The young man runs him through, and the Israelites go home. God repays Abimelech for the evil he did to his brothers and the Shechemites for their wickedness.
