Judges 9:4-6

Young's Literal Translation

⁴ and they give to him seventy silverings out of the house of Baal-Berith, and Abimelech hireth with them men, vain and unstable, and they go after him;

⁵ and he goeth into the house of his father at Ophrah, and slayeth his brethren, sons of Jerubbaal, seventy men, on one stone; and Jotham, youngest son of Jerubbaal, is left, for he was hidden.

⁶ And all the masters of Shechem are gathered together, and all the house of Millo, and come and cause Abimelech to reign for king at the oak of the camp which [is] in Shechem;
