(19) The middle watch.--The Jews anciently divided the night, from 6 P.M. to 6 A.M., into three watches (Exodus 14:24; 1Samuel 11:11). The subsequent division into four watches of three hours each was borrowed from the Romans (Matthew 14:25; Mark 6:48). At the beginning of the middle watch--i.e., soon after 10 at night--would be the time at which the host would be buried in their first sleep.

They had but newly set the watch.--Literally, scarcely--or. "just in rousing they roused the watch." The attack took place at the moment of confusion caused by changing the watch.

Verse 19. - The middle watch. The ancient Israelites divided the night into three watches of four hours each, from sunset to sunrise, i.e. from six p.m. to six a.m. The first watch, from six to ten, is not mentioned in the Old Testament; but we have the middle watch mentioned here (from ten to two), and the morning watch (from two till six): Exodus 14:24 and 1 Samuel 11:11. According to this, Gideon's attack would have taken place soon after ten p.m., or towards eleven, the time when the sleep would be the deepest, the watchmen of the first watch having lately fallen into their first sleep. The later Israelites adopted the Roman division of the night into four watches (Matthew 14:25; Mark 6:48; cf. Luke 12:38; Mark 13:35).

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, 2Co 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.So Gideon, and the one hundred men that were with him,.... Which was one of the three companies his army was divided into, and which company he had the command of particularly:

came unto the outside of the camp, in the beginning of the middle watch; the second watch, for the night was divided into three watches; for though in later times there were four watches, among the Romans (h), and which the Jews received from them; hence in the New Testament we read of the fourth watch; yet in earlier times, with the Jews and other eastern nations, there were but three watches, as affirmed by Jarchi and Kimchi on the place: and very wisely did Gideon fix on this watch for the time of his coming; for had he come at the first watch, many as yet might not have been in bed, or at least not fallen asleep; and had he come in the third watch, many might have been awake out of their sleep, and others up; but he took this time, a little after midnight, in the dead of the night, when the whole army was fast asleep:

and they had but newly set the watch; the first watch were just gone off, and the second were placed in their room; but since such an observation seems in a good measure unnecessary, for as Gideon came in the beginning of the watch it must in course be newly set; rather the words may be rendered, "in raising they raised up the watch" (i); that is, Gideon and his men did it by their approach; and they might call to them on purpose to give the alarm to the army, who upon that would at once hear the sound of the trumpets, and the clattering of the pitchers, and see the torches burning, to their great surprise:

and they blew the trumpets, and brake the pitchers that were in their hands; as soon as they came up to the watch and had raised them; this did Gideon and his hundred men.
