Judges 9:22-24
New International Version
22 After Abimelek had governed Israel three years, 23 God stirred up animosity between Abimelek and the citizens of Shechem so that they acted treacherously against Abimelek. 24 God did this in order that the crime against Jerub-Baal’s seventy sons, the shedding of their blood, might be avenged on their brother Abimelek and on the citizens of Shechem, who had helped him murder his brothers.
