Judges 7:7, 10-11, 18, 22

   7 And the LORD said unto Gideon, By the three hundred men that lapped will I save you, and deliver the Midianites into thine hand: and let all the [other] people go every man unto his place. ...

   10 But if thou fear to go down, go thou with Phurah thy servant down to the host: And thou shalt hear what they say; and afterward shall thine hands be strengthened to go down unto the host. Then went he down with Phurah his servant unto the outside of the armed men that [were] in the host. ...

   18 When I blow with a trumpet, I and all that [are] with me, then blow ye the trumpets also on every side of all the camp, and say, [The sword] of the LORD, and of Gideon. ...

   22 And the three hundred blew the trumpets, and the LORD set every man's sword against his fellow, even throughout all the host: and the host fled to Bethshittah in Zererath, [and] to the border of Abelmeholah, unto Tabbath.
