This plan of omnipotence so astonishing as it appears to human reason, was evidently intended for the glory of God, and the exercise of the faith of Israel. But as the ark, in this instance as in the former, at the fording of Jordan, formed the principal object, how sweetly when beheld and explained in a gospel sense, doth it set forth the sure victory of God's people, before whom Jesus goes, leading on his army to conquest. The Lord had promised Israel that his people should possess nations, whose cities were great and fenced up to heaven. And here he graciously undertook to raze those walls to the ground before them. Deuteronomy 9:1.

3 And ye shall compass the city, all ye men of war, and go round about the city once. Thus shalt thou do six days.
4 And seven priests shall bear before the ark seven trumpets of rams' horns: and the seventh day ye shall compass the city seven times, and the priests shall blow with the trumpets.
5 And it shall come to pass, that when they make a long blast with the ram's horn, and when ye hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat,a and the people shall ascend up every man straight before him.
