16 After he divided the three hundred men into three companies, and put trumpets into the hands of all of them, and empty jars, with torches inside the jars, 17 he said to them, "Look at me, and do the same; when I come to the outskirts of the camp, do as I do. 18 When I blow the trumpet, I and all who are with me, then you also blow the trumpets around the whole camp, and shout, "For the Lord and for Gideon!' " 19 So Gideon and the hundred who were with him came to the outskirts of the camp at the beginning of the middle watch, when they had just set the watch; and they blew the trumpets and smashed the jars that were in their hands. 20 So the three companies blew the trumpets and broke the jars, holding in their left hands the torches, and in their right hands the trumpets to blow; and they cried, "A sword for the Lord and for Gideon!" 21 Every man stood in his place all around the camp, and all the men in camp ran; they cried out and fled. 22 When they blew the three hundred trumpets, the Lord set every man's sword against his fellow and against all the army; and the army fled as far as Beth-shittah toward Zererah, as far as the border of Abel-meholah, by Tabbath.
23 And the men of Israel were called out from Naphtali and from Asher and from all Manasseh, and they pursued after the Midianites. 24 Then Gideon sent messengers throughout all the hill country of Ephraim, saying, "Come down against the Midianites and seize the waters against them, as far as Beth-barah, and also the Jordan." So all the men of Ephraim were called out, and they seized the waters as far as Beth-barah, and also the Jordan.

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.

(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.
