Judges 7:18-20

18When I and all who are with me blow the trumpet, then you also blow the trumpets all around the camp and say, ‘For the Lord and for Gideon.’”

19So Gideon and the hundred men who were with him came to the outskirts of the camp at the beginning of the middle watch, when they had just posted the watch; and they blew the trumpets and smashed the pitchers that were in their hands. 20When the three 1companies blew the trumpets and broke the pitchers, they held the torches in their left hands and the trumpets in their right hands for blowing, and cried, “A sword for the Lord and for Gideon!”
