16 He divided the 300 men into three groups and gave each man a ram's horn and a clay jar with a torch in it. 17 Then he said to them, "Keep your eyes on me. When I come to the edge of the camp, do just as I do. 18 As soon as I and those with me blow the rams' horns, blow your horns, too, all around the entire camp, and shout, 'For the Lord and for Gideon!'" 19 It was just after midnight, after the changing of the guard, when Gideon and the 100 men with him reached the edge of the Midianite camp. Suddenly, they blew the rams' horns and broke their clay jars. 20 Then all three groups blew their horns and broke their jars. They held the blazing torches in their left hands and the horns in their right hands, and they all shouted, "A sword for the Lord and for Gideon!" 21 Each man stood at his position around the camp and watched as all the Midianites rushed around in a panic, shouting as they ran to escape. 22 When the 300 Israelites blew their rams' horns, the Lord caused the warriors in the camp to fight against each other with their swords. Those who were not killed fled to places as far away as Beth-shittah near Zererah and to the border of Abel-meholah near Tabbath.

Commentary on Judges 7:16-22

(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.
