Gideon had threescore and ten sons of his body begotten: for he had many wives. Judges 8:30
Abimelech ... slew his brethren ... threescore and ten persons, upon one stone. Yet Jotham the youngest son of Jerubbaal [Gideon] was left; for he hid himself. Judges 9:4-5
God sent an evil spirit between Abimelech and the men of Shechem ... That the cruelty done to the threescore and ten sons of Jerubbaal might come, and their blood be laid upon Abimelech their brother, which slew them; and upon the men of Shechem, which aided him in the killing of his brethren. Judges 9:23-24
