And it came to pass, when Joshua had spoken unto the people, that the seven priests bearing the seven trumpets of rams' horns passed on before the LORD, and blew with the trumpets: and the ark of the covenant of the LORD followed them.

AD 423
Last Sunday we said that the walls of Jericho were laid waste by the priestly trumpets and that, contrary to order and nature, an unfeeling thing gave way before the sacred sounds with a kind of dread of the threat, and everything so collapsed at the loud noise that the most solid fortifications fell to the ground and the sinful people remained without protection. The one occurred lest resistance be offered for any amount of time, the other so that they would be the more easily captured.
But we have said that all these things were done then in symbol, for we believe that the priestly trumpets of that age were nothing other than the preaching of the priests of this age, by which we do not cease to announce, with a dreadful sound, something harsh to sinners, to speak of what is dismal, and to strike the ears of evildoers with, as it were, a threatening roar, since no one can resist the sacred sounds and no one can gainsay them. For how could feeling creatures not tremble at the word of God when at that time even unfeeling ones were shaken? And how could human hardheartedness resist what a stone fortification could not withstand? For just as, when the stone walls were destroyed, the clash of the trumpets reached the people within, so also now, when evil thoughts have been destroyed, the preaching of the priests penetrates to the bare parts of the soul, for the soul is found bare before the Word of God when its every evil deed is destroyed. And that the soul is bare before God the holy apostle says, “But all things are bare and uncovered to his eyes.” In this regard, before the soul knows God and accepts the truth of the faith, it veils itself, so to speak, under superstitious works and surrounds itself with something like a wall of perversity, such that it might seem to be able to remain impregnable within the fortifications of its own evildoing. But when the sacred sound thunders, its rashness is overthrown, its thinking is destroyed, and all the defenses of its superstitions break asunder in such a way that, remaining unprotected, as it is written, the Word of God might penetrate even to the division of its spirit and its inmost parts. Just as the ring of the sacred sound destroyed, captured and took vengeance on a hardhearted people then, so also now the priestly preaching subjugates, captures and takes vengeance on a sinful people. - "Sermon 94.1"
