Judges 9:5–6

5 He went to his father’s house in Ophrah and killed his seventy brothers, the sons of Jerubbaal, on top of a large stone. But Jotham, the youngest son of Jerubbaal, survived, because he hid. 6 Then all the citizens of Shechem and of Beth-millo gathered together and proceeded to make Abimelech king at the oak of the pillar in Shechem.
