Judges 9:22-25

22Abimelech ruled over Israel three years.

23And God sent an evil spirit between Abimelech and the leaders of Shechem, and the leaders of Shechem dealt treacherously with Abimelech,

24that the violence done to the seventy sons of Jerubbaal might come, and their blood be laid on Abimelech their brother, who killed them, and on the men of Shechem, who strengthened his hands to kill his brothers.

25And the leaders of Shechem put men in ambush against him on the mountaintops, and they robbed all who passed by them along that way. And it was told to Abimelech.
