Judges 7:14-18

And his friend replied, “This is nothing other than the sword of Gideon the son of Joash, a man of Israel; God has handed over to him Midian and all the camp.”

When Gideon heard the account of the dream and its interpretation, he bowed in worship. Then he returned to the camp of Israel and said, “Arise, for the Lord has handed over to you the camp of Midian!”

And he divided the three hundred men into three units, and he put trumpets and empty pitchers into the hands of all of them, with torches inside the pitchers.

Then he said to them, “Look at me and do likewise. And behold, when I come to the outskirts of the camp, do as I do.

When I and all who are with me blow the trumpet, then you also blow the trumpets around the entire camp and say, ‘For the Lord and for Gideon!’ ” Confusion of the Enemy
