Judges 20:12

8 Then all the people stood as one man and said, “Not one of us will return to his tent or to his house.

9 Now this is what we will do to Gibeah: We will go against it as the lot dictates.

10 We will take ten men out of every hundred from all the tribes of Israel, and a hundred out of every thousand, and a thousand out of every ten thousand, to supply provisions for the army when they go to Gibeah in Benjamin to punish them for the atrocity they have committed in Israel.”

11 So all the men of Israel gathered as one man, united against the city.

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

13 Hand over the wicked men of Gibeah so we can put them to death and purge Israel of this evil.” But the Benjamites refused to heed the voice of their fellow Israelites.

14 And from their cities they came together at Gibeah to go out and fight against the Israelites.

15 On that day the Benjamites mobilized 26,000 swordsmen from their cities, in addition to the 700 select men of Gibeah.

16 Among all these soldiers there were 700 select left-handers, each of whom could sling a stone at a hair without missing.
