Judges 20:14-16

Then the people of Benjamin came together out of the cities to Gibeah to go out to battle against the people of Israel. And the people of Benjamin mustered out of their cities on that day 26,000 men who drew the sword, besides the inhabitants of Gibeah, who mustered 700 chosen men. Among all these were 700 chosen men who were left-handed; every one could sling a stone at a hair and not miss.
