31:6 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.
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.
