Judges 9:1-6

Now Abimelech the son of Jerubbaal (Gideon) went to Shechem to his mother’s relatives, and said to them and to the whole clan of the household of his mother’s father, “Speak now in the hearing of all the leaders of Shechem, ‘Which is better for you, that seventy men, all of the sons of Jerubbaal rule over you, or that one man rule over you?’ Also, remember that I am your own bone and flesh.” So his mother’s relatives spoke all these words concerning him so that all the leaders of Shechem could hear; and their hearts were inclined to follow Abimelech, for they said, “He is our relative.” And they gave him seventy pieces of silver from the house of Baal-berith, with which Abimelech hired worthless and undisciplined men, and they followed (supported) him. Then he went to his father’s house at Ophrah and murdered his brothers the sons of Jerubbaal, seventy men, [in a public execution] on one stone. But Jotham the youngest son of Jerubbaal was left alive, because he had hidden himself. All the men of Shechem and all of Beth-millo assembled together, and they went and made Abimelech king, by the oak (terebinth) of the pillar (memorial stone) at Shechem.
