Judges 20:14

12The tribes of Israel sent men through all the tribe of Benjamin, saying, “What wickedness is this that has happened among you?

13Now therefore deliver up the men, the wicked fellows who are in Gibeah, that we may put them to death and put away evil from Israel.” But Benjamin would not listen to the voice of their brothers, the children of Israel.

14The children of Benjamin gathered themselves together out of the cities to Gibeah, to go out to battle against the children of Israel.

15The children of Benjamin were counted on that day out of the cities twenty-six thousand men who drew the sword, in addition to the inhabitants of Gibeah, who were counted seven hundred chosen men.

16Among all these soldiers there were seven hundred chosen men who were left-handed. Every one of them could sling a stone at a hair and not miss.
