Judges 9:5

9:5 He went to his father’s home in Ophrah and murdered his half-brothers, the seventy legitimate sons of Jerub-Baal, on one stone. Only Jotham, Jerub-Baal’s youngest son, escaped, because he hid.

Judges 9:16-19

9:16 “Now, if you have shown loyalty and integrity when you made Abimelech king, if you have done right to Jerub-Baal and his family, if you have properly repaid him – 9:17 my father fought for you; he risked his life and delivered you from Midian’s power. 9:18 But you have attacked my father’s family today. You murdered his seventy legitimate sons on one stone and made Abimelech, the son of his female slave, king over the leaders of Shechem, just because he is your close relative. 9:19 So if you have shown loyalty and integrity to Jerub-Baal and his family today, then may Abimelech bring you happiness and may you bring him happiness!
