Now Barak chased the chariots and the army all the way to Harosheth Haggoyim. Sisera's whole army died by the edge of the sword; not even one survived!

He said to them, "Watch me and do as I do. Watch closely! I am going to the edge of the camp. Do as I do!

Gideon took a hundred men to the edge of the camp at the beginning of the middle watch, just after they had changed the guards. They blew their trumpets and broke the jars they were carrying.
