And you would not err in identifying the sound of the trumpet with the preaching of the Gospel heard in all the world. For as the trumpet is the loudest of all musical instruments, it seems a fit symbol to shew forth that the teaching given to all men about Christ is proclaimed in stronger and louder tones than any other teaching has ever been, by which as by a trumpet for the hearing of all men the Holy Spirit shouts and cries what follows in this Psalm, "Sing to the Lord, sing, sing to our King, sing, That God is King "not only of the Jewish race in the future, he says, but "of all the earth, sing with understanding."
