We have here directions concerning the public notices that were to be given to the people upon several occasions by sound of trumpet. In a thing of this nature, one would think, Moses needed not to have been taught of God: his own reason might teach him the conveniency of trumpets; but the constitution of Israel was to be in every thing divine, and therefore even in this matter, small as it seems. Moses is here directed, 1. About the making of them. They must be made of silver; not cast but of beaten work (as some read it), the matter and shape, no doubt, very fit for the purpose. He was now ordered to make but two, because there were but two priests to use them. But in Solomon's time we read of 120 priests sounding with trumpets, Ch2 5:12. The form of these trumpets is supposed to have been much like ours at this day. 2. Who were to make use of them; not any inferior person, but the priests themselves, the sons of Aaron, Num 10:8. As great as they were, they must not think it a disparagement to them to be trumpeters in the house of God; the meanest office there was honourable. This signified that the Lord's ministers should lift up their voice like a trumpet, to show people their sins (Isa 58:1), to call them to Christ, Isa 27:13. 3. Upon what occasions the trumpets were to be sounded. (1.) For the calling of assemblies, Num 10:2. Thus they are told to blow the trumpet in Zion for the calling of a solemn assembly together, to sanctify a fast, Joe 2:15. Public notice ought to be given of the time and place of religious assemblies; for the invitation to the benefit or ordinances is general: whoever will, let him come. wisdom cries in the chief places of concourse. But, that the trumpet might not give an uncertain sound, they are directed, if only the princes and elders were to meet, to blow but one of the trumpets; less should serve to call them together, who ought to be examples of forwardness in any thing that is good: but, if the body of the people were to be called together, both the trumpets must be sounded, that they might be heard at the greater distance. In allusion to this, they are said to be blessed that hear the joyful sound (Psa 89:15), that is, that are invited and called upon to wait upon God in public ordinances, Psa 122:1. And the general assembly at the great day will be summoned by the sound of the archangel's trumpet, Mat 24:31. (2.) For the journeying of the camps, to give notice when each squadron must move; for no man's voice could reach to give the word of command: soldiers with us that are well disciplined may be exercised by beat of drums. When the trumpets were blown for this purpose, they mustsound an alarm (Num 10:5), a broken, quavering, interrupted sound, which was proper to excite and encourage the minds of people in their marches against their enemies; whereas a continued equal sound was more proper for the calling of the assembly together (Num 10:7): yet when the people were called together to deprecate God's judgments we find an alarm sounded, Joe 2:1. At the first sounding, Judah's squadron marched, at the second Reuben's, at the third Ephraim's, at the fourth Dan's, Num 10:5, Num 10:6. And some think that this was intended to sanctify their marches, for thus were proclaimed by the priests, who were God's mouth to the people, not only the divine orders given them to move, but the divine blessing upon them in all their motions. He that hath ears, let him hear that God is with them of a truth. King Abijah valued himself and his army very much upon this (Ch2 13:12), God himself is with us for our captain and his priests with sounding trumpets. (3.) For the animating and encouraging of their armies, when they went out in battle (Num 10:9): "If you go to war, blow with the trumpets, signifying thereby your appeal to heaven for the decision of the controversy, and your prayer to God to give you victory; and God will own this his own institution, and you shall be remembered before the Lord your God." God will take notice of this sound of the trumpet, and be engaged to fight their battles, and let all the people take notice of it, and be encouraged to fight his, as David, when he heard a sound of a going upon the tops of the mulberry trees. Not that God needed to be awaked by sound of trumpet any more than Christ needed to be awaked by his disciples in the storm, Mat 8:25. But where he intends mercy it is his will that we should solicit it; ministers must stir up the good soldiers of Jesus Christ to fight manfully against sin, the world, and the devil, by assuring them that Christ is the captain of their salvation, and will tread Satan under their feet. (4.) For the solemnizing of their sacred feasts, Mat 8:10. One of their feasts was called a memorial of the blowing of trumpets, Lev 23:23, etc. And it should seem they were thus to grace the solemnity of all their feasts (Psa 81:3), and their sacrifices (Ch2 29:27), to intimate with what joy and delight they performed their duty to God, and to raise the minds of those that attended the services to a holy triumph in the God they worshipped. And then their performances were for a memorial before God; for he takes pleasure in our religious exercises when we take pleasure in them. Holy work should be done with holy joy.

Here is, I. A general account of the removal of the camp of Israel from mount Sinai, before which mountain it had lain now about a year, in which time and place a great deal of memorable business was done. Of this removal, it should seem, God gave them notice some time before (Deu 1:6, Deu 1:7): You have dwelt long enough in this mountain, turn you and take your journey towards the land of promise. The apostle tells us that mount Sinai genders to bondage (Gal 4:24), and signifies the law there given, which is of use indeed as a schoolmaster to bring us to Christ, yet we must not rest in it, but advance towards the joys and liberties of the children of God, for our happiness is conferred not by the law, but by promise. Observe, 1. The signal given (Num 10:11): The cloud was taken up, and we may suppose it stood for some time, till they were ready to march; and a great deal of work it was to take down all those tents, and pack up all those goods that they had there; but every family being employed about its own, and all at the same time, many hands made quick work of it. 2. The march began: They took their journey according to the commandment of the Lord, and just as the cloud led them, Num 10:13. Some think that mention is thus frequently made in this and the foregoing chapter of the commandment of the Lord, guiding and governing them in all their travels, to obviate the calumny and reproach which were afterwards thrown upon Israel, that they tarried so long in the wilderness, because they had lost themselves there, and could not find the way out. No, the matter was not so; in every stage, in every step, they were under divine direction; and, if they knew not where they were, yet he that led them knew. Note, Those that have given up themselves to the direction of God's word and Spirit steer a steady course, even when they seem to be bewildered. While they are sure they cannot lose their God and guide, they need not fear losing their way. 3. The place they rested in, after three days' march: They went out of the wilderness of Sinai, and rested in the wilderness of Paran. Note, All our removals in this world are but from one wilderness to another. The changes which we think will be for the better do not always prove so; while we carry about with us, wherever we go, the common infirmities of human nature, we must expect, wherever we go, to meet with its common calamities; we shall never be at rest, never at home, till we come to heaven, and all will be well there. II. A particular draught of the order of their march, according to the late model. 1. Judah's squadron marched first, Num 10:14-16. The leading standard, now lodged with that tribe, was an earnest of the sceptre which in David's time should be committed to it, and looked further to the captain of our salvation, of whom it was likewise foretold that unto him should the gathering of the people be. 2. Then came those two families of the Levites which were entrusted to carry the tabernacle. As soon as ever the cloud was taken up, the tabernacle was taken down, and packed up for removing, Num 10:17. And here the six wagons came laden with the more bulky part of the tabernacle. This frequent removing of the tabernacle in all their journeys signified the movableness of that ceremonial dispensation. That which was so often shifted would at length vanish away, Heb 8:13. 3. Reuben's squadron marched forward next, taking place after Judah, according to the commandment of the Lord, Num 10:18-20. 4. Then the Kohathites followed with their charge, the sacred furniture of the tabernacle, in the midst of the camp, the safest and most honourable place, Num 10:21. And they (that is, says the margin, the Gershonites and Merarites) did set up the tabernacle against they came; and perhaps it is expressed thus generally because, if there was occasion, not those Levites only, but the other Israelites that were in the first squadron, lent a hand to the tabernacle to hasten the rearing of it up, even before they set up their own tents. 5. Ephraim's squadron followed next after the ark (Num 10:22-24), to which some think the psalmist alludes when he prays (Psa 80:2), Before Ephraim, Benjamin, and Manasseh, the three tribes that composed this squadron, stir up thy strength (and the ark is called his strength, Psa 78:61), and come and save us. 6. Dan's squadron followed last, Num 10:25-27. It is called the rearward, or gathering host, of all the camps, because it gathered up all that were left behind; not the women and children (these we may suppose were taken care of by the heads of their families in their respective tribes), but all the unclean, the mixed multitude, and all that were weak and feeble, and cast behind in their march. Note, He that leadeth Joseph like a flock has a tender regard to the hindmost (Eze 34:16), that cannot keep pace with the rest, and of all that are given him he will lose none, Joh 17:11.
