Judges 9:18-20

and you have risen up against my father’s house today and have slain his sons, seventy persons, on one stone, and have made Abimelech, the son of his female servant, king over the men of Shechem, because he is your brother); if you then have dealt truly and righteously with Jerubbaal and with his house today, then rejoice in Abimelech, and let him also rejoice in you; but if not, let fire come out from Abimelech and devour the men of Shechem and the house of Millo; and let fire come out from the men of Shechem and from the house of Millo and devour Abimelech.”
