VIII. At last they were to give a shout, and did so, and immediately the walls fell, v. 16. This was a shout for mastery, a triumphant shout; the shout of a king is among them, Num. xxiii. 21. This was a shout of faith; they believed that the walls of Jericho would fall, and by this faith the walls were thrown down. It was a shot of prayer, an echo to the sound of the trumpets which proclaimed the promise that God would remember them; with one accord, as one man, they cry to heaven for help, and help comes in. Some allude to this to show that we must never expect a complete victory over our own corruptions till the very evening of our last day, and then we shall shout in triumph over them, when we come to the number and measure of our perfection, as bishop Hall expresses it. A good heart (says he) groans under the sense of his infirmities, fain would be rid of them, and strives and prays, but, when all is done, until the end of the seventh day it cannot be; then judgment shall be brought forth unto victory. And at the end of time, when our Lord shall descend from heaven with a shout, and the sound of a trumpet, Satan's kingdom shall be completely ruined, and not till then, when all opposing rule, principality, and power, shall be effectually and eternally put down.
