16 Then he divided the three hundred men into three companies, and he put a trumpet into every man's hand, with empty pitchers, and torches inside the pitchers. 17 And he said to them, "Look at me and do likewise; watch, and when I come to the edge of the camp you shall do as I do: 18 When I blow the trumpet, I and all who are with me, then you also blow the trumpets on every side of the whole camp, and say, 'The sword of the Lord and of Gideon!' " 19 So Gideon and the hundred men who were with him came to the outpost of the camp at the beginning of the middle watch, just as they had posted the watch; and they blew the trumpets and broke the pitchers that were in their hands. 20 Then the three companies blew the trumpets and broke the pitchers--they held the torches in their left hands and the trumpets in their right hands for blowing--and they cried, "The sword of the Lord and of Gideon!" 21 And every man stood in his place all around the camp; and the whole army ran and cried out and fled. 22 When the three hundred blew the trumpets, the Lord set every man's sword against his companion throughout the whole camp; and the army fled to Beth Acacia, toward Zererah, as far as the border of Abel Meholah, by Tabbath.
23 And the men of Israel gathered together from Naphtali, Asher, and all Manasseh, and pursued the Midianites. 24 Then Gideon sent messengers throughout all the mountains of Ephraim, saying, "Come down against the Midianites, and seize from them the watering places as far as Beth Barah and the Jordan." Then all the men of Ephraim gathered together and seized the watering places as far as Beth Barah and the Jordan.

(Read Judges 7:16-22)
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.
Commentary on Judges 7:23-25
(Read Judges 7:23-25)
Two chief commanders of the host of Midian were taken and slain by the men of Ephraim. It were to be wished that we all did as these did, and that where help is needed, that it were willingly and readily performed by another. And that if there were any excellent and profitable matter begun, we were willing to have fellow-labourers to the finishing and perfecting the same, and not, as often, hinder one another.
