“Now Zebah and Zalmunna were in Karkor with their army, about fifteen thousand men, all who were left of all the army of the people of the East. For one hundred twenty thousand men bearing arms had fallen. So Gideon went up by the caravan route east of Nobah and Jogbehah. He attacked the army. For the army was off its guard. Zebah and Zalmunna fled. He pursued them. He took the two kings of Midian, Zebah and Zalmunna. Then he threw all the army into a panic.”
Wow! Gideon’s 300 men had already defeated 120,000 men so that only about 15,000 were left. These are amazing incredible numbers. Once again, Gideon used a surprise attack. This is the only mention of Karkor. The whole Midianite army was in panic as it lost its 2 leaders. It is not clear how these 300 men through 15,000 into a panic, but that is the mode of operation of Gideon.
