Judges 9:22–25
After Abimelech had reigned over Israel for three years, / God sent a spirit of animosity between Abimelech and the leaders of Shechem and caused them to treat Abimelech deceitfully, / in order that the crime against the seventy sons of Jerubbaal might come to justice and their blood be avenged on their brother Abimelech and on the leaders of Shechem, who had helped him murder his brothers.
