Phinehas - He was marked out as the fitting director of the expedition by his conduct (compare Numbers 25:7-13) in the matter of Zimri and Cozbi.

With the holy instruments, and the trumpets - Or rather, "with the holy instruments, to wit, the trumpets," for the trumpets themselves seem to be the instruments intended.

A thousand of every tribe - Twelve thousand men in the whole. And Phinehas, the son of Eleazar; some think he was made general in this expedition, but this is not likely. The ark and its contents must proceed to this battle, because the battle was the Lord's, and he dwelt between the cherubim over the ark; and Phinehas, who had before got a grant in the eternal priesthood, was chosen to accompany the ark in place of his father Eleazar, who was probably now too far advanced in years to undergo the fatigue. Who then was general? Joshua, without doubt, though not here mentioned, because the battle being the Lord's, he alone is to have the supreme direction, and all the glory. Besides, it was an extraordinary war, and not conducted on the common principle, for we do not find that peace was offered to the Midianites, and that they refused it; see Deuteronomy 20:10, etc. In such a case only hostilities could lawfully commence; but they were sinners against God; the cup of their iniquity was full, and God thought proper to destroy them. Though a leader there certainly was, and Joshua was probably that leader, yet because God, for the above reason, was considered as commander-in-chief, therefore no one else is mentioned; for it is evident that the sole business of Phinehas was to take care of the holy instruments and to blow with the trumpet.

And Moses sent them to the war,.... Being mustered and armed:

a thousand of every tribe, them and Phinehas the son of Eleazar the priest to the war; which looks as if Phinehas was the general of this army; for Moses went not to the war, and no mention is made of Joshua, nor might it be proper for him, he being the successor of Moses, who was quickly to die; but it seems rather that there was no one person that had the command of the whole, but every captain commanded his own company; since, when Moses met them, and was angry with them for sparing the women, he does not address anyone as the chief commander, but all the officers, Numbers 31:14, however, it was very proper and prudent to send Phinehas with them, both on account of his office as a priest, to encourage the people, and because of his extraordinary zeal against the Midianites for what they had done, as appears by his slaying a prince of Simeon and a Midianitish princess in their uncleanness:

and he went with the holy instruments, and the trumpets to blow in his hand; by "the holy instruments", Aben Ezra understands the ark with what appertained to it, which in later times used to be carried out when the Israelites went to war, Joshua 6:4, and Jarchi interprets them of the ark and plate of gold (z) which was upon the forehead of the high priest; but what had Phinehas to do with this, who was but a common priest? though the Targum of Jonathan paraphrases it,"with the Urim and Thummim of holiness, to inquire by them;''and it appears, that sometimes a son of an high priest was intrusted with the ephod, to which the breastplate was fastened, which had the Urim and Thummim on it, and made use thereof to inquire by, as in the times of David, 1 Samuel 23:6, but it is the opinion of some learned men, and they may be in the right, that these instruments are no other than the trumpets, and who suppose the "vau" is not copulative, but explanative, so Ben Gersom, and read the words thus, "with the holy instruments, even", or, "that is, the trumpets" (a), the silver trumpets ordered to be made, Numbers 10:2 one of which was far the journey of the camps, and also to blow an alarm for war, and which was done by the priests; and so the Targum of Jonathan adds here,"to cause the camp of Israel to rest, and to cause it to go;''that is, to direct it when it should stop, and when it should move.

(z) So the Rabbins in Abendana in Miclol Yophi in loc. (a) "erantque tubae", Tigurine version; "id est tubae", Vatablus; "nempe tubae", Piscator; so Ainsworth.

And Moses sent them to the war, a thousand of every tribe, them and {b} Phinehas the son of Eleazar the priest, to the war, with the holy instruments, and the trumpets to blow in his hand.

(b) For his great zeal that he bare for the Lord, Nu 25:13.

31:6 Them and Phinehas - Who had the charge not of the army, as general, (an office never committed to a priest in all the Old Testament) but of the holy instruments, and was sent to encourage, and quicken, them in their enterprize. The holy instruments - The holy breast - plate, wherein was the Urim and Thummim, which was easily carried, and very useful in war upon many emergent occasions.

6. Moses sent . Eleazar the priest, to the war-Although it is not expressly mentioned, it is highly probable that Joshua was the general who conducted this war. The presence of the priest, who was always with the army (De 20:2), was necessary to preside over the Levites, who accompanied the expedition, and to inflame the courage of the combatants by his sacred services and counsels.

holy instruments-As neither the ark nor the Urim and Thummim were carried to the battlefield till a later period in the history of Israel, the "holy instruments" must mean the "trumpets" (Nu 10:9). And this view is agreeable to the text, by simply changing "and" into "even," as the Hebrew particle is frequently rendered.

31:1-6 All who, without commission from God, dare to execute private revenge, and who, from ambition, covetousness, or resentment, wage war and desolate kingdoms, must one day answer for it. But if God, instead of sending an earthquake, a pestilence, or a famine, be pleased to authorize and command any people to avenge his cause, such a commission surely is just and right. The Israelites could show such a commission, though no persons now can do so. Their wars were begun and carried on expressly by Divine direction, and they were enabled to conquer by miracles. Unless it can be proved that the wicked Canaanites did not deserve their doom, objectors only prove their dislike to God, and their love to his enemies. Man makes light of the evil of sin, but God abhors it. This explains the terrible executions of the nations which had filled the measure of their sins.
