Thematic Bible: Abimelech, killing his seventy brothers

And Abimelech son of Jerub-Baal went to Shechem, to the relatives of his mother, and he said to them and to the house of his mother's father, "{Speak to} the lords of Shechem, 'What [is] better for you, that seventy men all from the sons of Jerub-Baal rule over you, or that one man rules over you?' Remember that I [am] your bone and your flesh." And his mother's relatives spoke all these words concerning him {to} all the lords of Shechem; and {they supported Abimelech}, for they said, "He is our relative." read more.
