What did Gideon's men shout as they surrounded the Midianite camp?

Answer: A sword for the LORD and for Gideon!

After breaking their jars and blowing their horns they shouted this, and the whole Midianite army fled.

“The three companies blew their horns and shattered their jars. Holding the torches in their left hands and the horns in their right hands, they shouted, “A sword for the LORD and for Gideon!” Each Israelite took his position around the camp, and the entire Midianite army fled, crying out as they ran.”— Judges 7:20-21 (BSB)
