Judges 20:12-17

12Then the tribes of Israel sent men through the entire tribe of Benjamin, saying, “What is this evil thing that has been done among you?

13Now therefore, turn over the men [involved], the worthless and wicked men in Gibeah, so that we may put them to death and remove this wickedness from Israel.” But the Benjamites would not listen to the voice of their brothers, the sons of Israel.

14Then the [tribe of the] sons of Benjamin gathered from the cities to Gibeah, to go out to battle against the [other] sons of Israel.

15And the Benjamites assembled out of their cities at that time twenty-six thousand men who drew the sword, besides the inhabitants of Gibeah, who assembled seven hundred chosen men.

16Out of all these people were seven hundred choice left-handed men; each one could sling stones at [a target no wider than] a hair and not miss.

17Then the men of Israel, other than Benjamin, assembled four hundred thousand men who drew the sword; all of these were men of war.
