16 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 He said to them, “Watch me, and do likewise. Behold, when I come to the outermost part of the camp, it shall be that, as I do, so you shall do. 18 When I blow the trumpet, I and all who are with me, then blow the trumpets also on every side of all the camp, and shout, ‘For Yahweh and for Gideon!’” 19 So Gideon, and the hundred men who were with him, came to the outermost part of the camp in the beginning of the middle watch, when they had but newly set the watch: and they blew the trumpets, and broke in pieces the pitchers that were in their hands. 20 The three companies blew the trumpets, and broke the pitchers, and held the torches in their left hands, and the trumpets in their right hands with which to blow; and they shouted, “The sword of Yahweh and of Gideon!”

This method of defeating the Midianites may be alluded to, as exemplifying the destruction of the devil's kingdom in the world, by the preaching of the everlasting gospel, the sounding that trumpet, and the holding forth that light out of earthen vessels, for such are the ministers of the gospel, 2 Corinthians 4:6,7. God chose the foolish things of the world to confound the wise, a barley-cake to overthrow the tents of Midian, that the excellency of the power might be of God only. The gospel is a sword, not in the hand, but in the mouth: the sword of the Lord and of Gideon; of God and Jesus Christ, of Him that sits on the throne and the Lamb. The wicked are often led to avenge the cause of God upon each other, under the power of their delusions, and the fury of their passions. See also how God often makes the enemies of the church instruments to destroy one another; it is a pity that the church's friends should ever act like them.
