Judges 20:14-16

14Instead, the children of Benjamin gathered together from their cities to Gibeah, to go to battle against the children of Israel.

15And from their cities at that time the children of Benjamin numbered twenty-six thousand men who drew the sword, besides the inhabitants of Gibeah, who numbered seven hundred select men.

16Among all this people were seven hundred select men who were left-handed; every one could sling a stone at a hair’s breadth and not miss.
