Judges 8:10-12

10Now Zebah and Zalmunna were in Karkor with their armies, about fifteen thousand [fighting] men, all who were left of the entire army of the sons of the east; for a hundred and twenty thousand swordsmen had fallen.

11Gideon went up by the route of those who lived in tents to the east of Nobah and Jogbehah, and he attacked their camp when the camp was unsuspecting.

12When Zebah and Zalmunna fled, he pursued them and captured the two kings of Midian, Zebah and Zalmunna, and terrified the entire army.
