101 The Lord spoke to Moses, saying: 2 Make two silver trumpets; you shall make them of hammered work; and you shall use them for summoning the congregation, and for breaking camp. 3 When both are blown, the whole congregation shall assemble before you at the entrance of the tent of meeting. 4 But if only one is blown, then the leaders, the heads of the tribes of Israel, shall assemble before you. 5 When you blow an alarm, the camps on the east side shall set out; 6 when you blow a second alarm, the camps on the south side shall set out. An alarm is to be blown whenever they are to set out. 7 But when the assembly is to be gathered, you shall blow, but you shall not sound an alarm. 8 The sons of Aaron, the priests, shall blow the trumpets; this shall be a perpetual institution for you throughout your generations.

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.
