Judges 8:10-11

10Now Zebah and Zalmunna were in Karkor, and with them was their army of about fifteen thousand men, who were all those left of the entire army of the people of the east. Those who had been killed were one hundred twenty thousand armed men.

11Gideon traveled on the caravan route east of Nobah and Jogbehah and attacked their army while the army felt secure.
