SEV Biblia, Chapter 10:8
Y los hijos de Aarón, los sacerdotes, tocarán las trompetas; y las tendréis por estatuto perpetuo por vuestras generaciones.
John Gill's Bible Commentary
Ver. 8. And the sons of Aaron the priests shall blow with the trumpets , etc.] Eleazar and Ithamar, the one with the one and the other with the other, there being at first but two, as there were but two priests; but in Solomon’s time there were an hundred twenty priests, and as many trumpets, ( 2 Chronicles 5:12); hence Maimonides says f102 , there were never fewer than two trumpets, nor more than an hundred twenty; and they shall be to you for an ordinance for ever throughout your generations : for they were not only for present use, for the journeying of the camps in the wilderness, but for calling together the assembly in later times, as well as for other uses next mentioned; which would obtain in future ages till the coming of Christ, and even under the Gospel dispensation the mystical use of them continues, the preaching of the everlasting Gospel.
Matthew Henry Commentary
Verses 1-10 - 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 typif the preached gospel. It sounds an alarm to sinners, calls them to repent, proclaims liberty to the captives and slaves of Satan, an 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 distinct sound, according to the persons addressed, or the en 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. (Nu 10:11-28)
