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.

Make thee two trumpets of silver,.... A metal very valuable and precious, durable, and fit for sound; only two are ordered, Aaron having but two sons, Eleazar and Ithamar, who were to blow with them, Num 10:8; for though Moses's order is, "make thee", or for thee, yet not for his own use, but for the priests to use when he should order them: the Targum of Jonathan adds, of what is thine own, as if they were to be made at his own expense; but others say, and which is more probable, that they were to be made at the public expense: Josephus (i) gives a description of them, and says, that they were little less than a cubit long, the pipe of them narrow, but broader about the mouth to receive the breath, and ended like a bell; they seem to be much of the shape of our trumpets: these trumpets were an emblem of the ministry of the Gospel, called the great trumpet, and in the ministration of which, the preachers of it are to lift up their voice like a trumpet, to show men their perishing condition through sin, and to encourage them, as such who are ready to perish, to come to Christ for salvation, Isa 27:13; the Gospel is comparable to silver, being fetched out of the mines of the sacred Scriptures, pure and free from the dross of errors and human inventions, will bear to be tried by the standard of the word, and is lasting and durable, yea, the everlasting Gospel; as well as valuable and precious, containing the unsearchable riches of Christ, &c. treasures of divine truths, comparable to gold, silver, and precious stones; yea, it is more valuable and precious than silver, not to be obtained by that, more profitable and useful, more satisfying and lasting: the number two may be applicable to the two dispensations, under which the Gospel has been ministered, directing to the same Saviour, and to the same way of salvation, by his grace, his blood, righteousness, and sacrifice; and to the two Testaments, which agree in the same truths respecting his person, offices, obedience, sufferings, and death; and to the prophets and apostles of both dispensations and testaments, who have united in laying Christ as the foundation; and also to the two witnesses that are still to prophecy in sackcloth, that is, preach the Gospel and blow the trumpet of it: Rev 11:3.

of an whole piece shall thou make them; of one solid mass of silver, beaten with an hammer, as Jarchi, such a piece as the candlestick was made of in Exo 25:31, where the same word is used as here, and rendered "beaten work": this may denote the pure and unmixed Gospel of Christ, having no dross, nor bad nor base metal of human corruptions in it; no jar, discord, or contradiction in it, but all in perfect harmony and agreement; and the whole of it, no part of it dropped or concealed; and the ministry of it, laboured by those employed in it, who study to show themselves workmen that need not be ashamed:

that thou mayest use them for the calling the assembly; the body of the people of Israel, either on civil or sacred accounts, see Joe 1:15; the ministry of the Gospel is for the calling and gathering of souls to Christ, and to his churches; even the remnant of Israel, all that are given to Christ and redeemed by his blood, whether Jews or Gentiles; these are gathered out of the world, which is an act of distinguishing grace; it is by means of the Gospel trumpet that they are awakened, and quickened, and directed to Christ:

and for the journeying of the camps: both of the four camps of the Israelites, and the camp of the Levites, to direct them when they should set forward on a journey: and of like use is the ministry of the Gospel; saints are pilgrims and travellers here; they are passing through a wilderness, their way is attended with many difficulties; Canaan is the place they are travelling to, and the Gospel is of singular use to them by the way, both to refresh them with its joyful sound, and to direct them in the path in which they should go.
