Jamieson, Fausset y Brown sobre Josué 3

5. Joshua said unto the people--rather "had said," for as he speaks of "to-morrow," the address must have been made previous to the day of crossing, and the sanctification was in all probability the same as Moses had commanded before the giving of the law, consisting of an outward cleansing (Ex 19:10-15) preparatory to that serious and devout state of mind with which so great a manifestation should be witnessed.

6. Joshua spake unto the priests--This order to the priests would be given privately, and involving as it did an important change in the established order of march, it must be considered as announced in the name and by the authority of God. Moreover, as soon as the priests stepped into the waters of Jordan, they were to stand still. The ark was to accomplish what had been done by the rod of Moses. Jos 3:7, 8. The Lord Encourages Joshua.

7-8. the Lord said to Joshua, This day will I ... magnify thee in the sight of all Israel--Joshua had already received distinguished honors (Ex 24:13; De 31:7). But a higher token of the divine favor was now to be publicly bestowed on him, and evidence given in the same unmistakable manner that his mission and authority were from God as was that of Moses (Ex 14:31).

Jos 3:9-13. Joshua Encourages the People. 9-13. Come hither, and hear the words of the Lord--It seems that the Israelites had no intimation how they were to cross the river till shortly before the event. The premonitory address of Joshua, taken in connection with the miraculous result exactly as he had described it, would tend to increase and confirm their faith in the God of their fathers as not a dull, senseless, inanimate thing like the idols of the nations, but a Being of life, power, and activity to defend them and work for them.

Jos 3:14-17. The Waters of Jordan Are Divided. 14-16. And it came to pass, when the people removed from their tents, &c.--To understand the scene described we must imagine the band of priests with the ark on their shoulders, standing on the depressed edge of the river, while the mass of the people were at a mile's distance. Suddenly the whole bed of the river was dried up; a spectacle the more extraordinary in that it took place in the time of harvest, corresponding to our April or May--when "the Jordan overfloweth all its banks." The original words may be more properly rendered "fills all its banks." Its channel, snow-fed from Lebanon, was at its greatest height--brimful; a translation which gives the only true description of the state of Jordan in harvest as observed by modern travellers. The river about Jericho is, in ordinary appearance, about fifty or sixty yards in breadth. But as seen in harvest, it is twice as broad; and in ancient times, when the hills on the right and left were much more drenched with rain and snow than since the forests have disappeared, the river must, from a greater accession of water, have been broader still than at harvest-time in the present day.

17. the priests ... and all the Israelites passed over on dry ground--the river about Jericho has a firm pebbly bottom, on which the host might pass, without inconvenience when the water was cleared off.
