Judges 8:10-11

10Now Zebah and Zalmunna were in Karkor with their army of about fifteen thousand men—all that were left of the armies of the people of the east. A hundred and twenty thousand swordsmen had already fallen. 11And Gideon went up by way of the caravan route east of Nobah and Jogbehah, and he attacked their army, taking them by surprise.
