'Seventy Sons' in the Bible

and to Gideon there have been seventy sons, coming out of his loin, for he had many wives;

for the coming in of the violence to the seventy sons of Jerubbaal, and of their blood to place it on Abimelech their brother, who slew them, and on the masters of Shechem, who strengthened his hands to slay his brethren.
