Judges 20:12-17

12And the tribes of Israel sent men through the tribe of Benjamin saying, “What is this wickedness that has taken place among you?

13Now therefore, give up the men, the worthless fellows that are in Gibeah, that we may put them to death and purge this evil from Israel.” But the children of Benjamin would not listen to the voice of their kinsmen Bnei-Yisrael.

14So the children of Benjamin were gathered from their towns to Gibeah, to go out to battle against Bnei-Yisrael.

15On that day the children of Benjamin mustered 26,000 swordsmen from the towns, besides the inhabitants of Gibeah, who numbered 700 chosen men.

16Out of all these troops there were 700 chosen men that were left-handed, each of whom could sling a stone at a hair and not miss.

17Meanwhile the men of Israel, apart from Benjamin, numbered 400,000 swordsmen; all men of war.
