101 And the Lord said to Moses, 2 Make two silver horns of hammered work, to be used for getting the people together and to give the sign for the moving of the tents. 3 When they are sounded, all the people are to come together to you at the door of the Tent of meeting. 4 If only one of them is sounded, then the chiefs, the heads of the thousands of Israel, are to come to you. 5 When a loud note is sounded, the tents placed on the east side are to go forward. 6 At the sound of a second loud note, the tents on the south side are to go forward: the loud note will be the sign to go forward. 7 But when all the people are to come together, the horn is to be sounded but not loudly. 8 The horns are to be sounded by the sons of Aaron, the priests; this is to be a law for you for ever, from generation to generation. 9 And if you go to war in your land against any who do you wrong, then let the loud note of the horn be sounded; and the Lord your God will keep you in mind and give you salvation from those who are against you. 10 And on days of joy and on your regular feasts and on the first day of every month, let the horns be sounded over your burned offerings and your peace-offerings; and they will put the Lord in mind of you: I am the Lord your God.

Here are directions concerning the public notices to be given the people by sound of trumpet. Their laws in every case were to be Divine, therefore, even in this matter Moses is directed. These trumpets typify the preached gospel. It sounds an alarm to sinners, calls them to repent, proclaims liberty to the captives and slaves of Satan, and collects the worshippers of God. It directs and encourages their heavenly journey; stirs them up to combat against the world and sin, encouraging them with the assurance of victory. It leads their attention to the sacrifice of Christ, and shows the Lord's presence for their protection. It is also necessary that the gospel trumpet give a distinct sound, according to the persons addressed, or the end proposed; whether to convince, humble, console, exhort, reprove, or teach. The sounding of the trumpet of the gospel is God's ordinance, and demands the attention of all to whom it is sent.
