Judges 7
16 Ref And he divided the three hundred men into three companies, and he put into the hands of all of them trumpets, and empty pitchers, with torches within the pitchers.
17 Ref And he said unto them, Look on me, and do likewise: and, behold, when I come to the outermost part of the camp, it shall be that, as I do, so shall ye do.
18 Ref When I blow the trumpet, I and all that are with me, then blow ye the trumpets also on every side of all the camp, and say, For Jehovah and for Gideon.
