He said, "They [were] my brothers, the sons of my mother. As Yahweh lives, if you had kept them alive I would not kill you."

And he went to his father's house at Ophrah, and he killed his brothers, the sons of Jerub-Baal, seventy men, on one stone. But Jotham the youngest son of Jerub-Baal survived, because he hid himself.

so that the violence done to the seventy brothers of Abimelech would be avenged and their blood be placed on Abimelech their brother, who killed them, and on the lords of Shechem, {who helped} to kill his brothers.

So God repaid the wickedness that Abimelech committed against his father by killing his seventy brothers.

So Jephthah fled from the presence of his brothers, and he lived in the land of Tob. And {outlaws} gathered around Jephthah and went with him.

His brothers and {his whole family} came down and picked him up; and they brought him up and buried him between Zorah and Eshtaol in the tomb of Manoah his father; he judged Israel twenty years.

So the man, the owner of the house, went out to them and said to them, "No, my brothers, do not act wickedly; since this man has come into my house, do not do this disgraceful thing.

And if their fathers or their brothers complain to us, we will say to them, 'Allow us to have them, because we did not capture a wife for each man in the battle, and because you did not give [them] to them, {or else} you would have been guilty.'"
