So the people shouted when the priests blew with the trumpets: and it came to pass, when the people heard the sound of the trumpet, and the people shouted with a great shout, that the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.
All Commentaries on Joshua 6:20 Go To Joshua 6
Augustine of Hippo
AD 430
So the walls of that city, called Jericho, which in the Hebrew tongue is said to mean moon, fell when they had been encircled seven times by the ark of the covenant. What, then, does the announcement of the kingdom of heaven portend—signified by the encircling of the ark—except that all the battlements of mortal life, that is, all the hope of this world, which is opposed to the hope of the world to come, will be destroyed by the sevenfold gift of the Holy Spirit, working through the free will? For, those walls fell of their own accord, not by any violent push of the ark in its circuit. There are other references in Scripture which suggest the church to us under the symbolism of the moon, as it makes its pilgrimage in this mortal life, amid toils and labors, far from that Jerusalem whose citizens are the holy angels.
