Judges 9:22-29

Abimelech ruled over Israel for three years. Then God sent an evil spirit between Abimelech and the leaders of Shechem; and the leaders of Shechem acted treacherously against Abimelech, so that the violence done to the seventy sons of Jerubbaal (Gideon) might come [on the guilty], and that their [innocent] blood might be laid on Abimelech their brother, who had killed them, and on the leaders of Shechem, who strengthened his hands (encouraged him) to kill his brothers. The leaders of Shechem set men in ambush against Abimelech on the mountaintops, and they robbed all who passed by them along the road; and it was reported to Abimelech. Now Gaal the son of Ebed came with his relatives, and moved into Shechem; and the leaders of Shechem trusted him. They went out into the field, gathered the grapes of their vineyard and trod them, and held a festival; and they entered the house of their god, and they ate and drank, and cursed Abimelech. Gaal the son of Ebed said, “Who is Abimelech, and who is Shechem, that we should serve him? Is he not [merely] the son of Jerubbaal and is Zebul not his lieutenant? Serve the men of Hamor the father (founder) of Shechem. Why then should we serve Abimelech? If only this people were under my authority! Then I would remove Abimelech and say to him, ‘Increase [the size of] your army and come out [to fight].’ ”
