Judges 9:22-24

Abimelech ruled over Israel for three years. Then God brought bad blood between Abimelech and Shechem’s leaders, who now worked treacherously behind his back. Violence boomeranged: The murderous violence that killed the seventy brothers, the sons of Jerub-Baal, was now loose among Abimelech and Shechem’s leaders, who had supported the violence.
