Judges 7:18-19

When I blow the trumpet, I and all who are with me, then you also blow the trumpets on every side of the whole camp, and say, ‘The sword of the LORD and of Gideon!’ ” So Gideon and the hundred men who were with him came to the outpost of the camp at the beginning of the middle watch, just as they had posted the watch; and they blew the trumpets and broke the pitchers that were in their hands.
