Judges 7:16-18 ▼

16 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.

17 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.

18 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!’”
