Verses 14-17 narrate the actual crossing. One long sentence, like the roll of an Atlantic wave, or a long-drawn shout of triumph, masses together the stages of the march; the breaking up of the encampment; the solemn advance of the ark, watched by the motionless crowd; its approach to the foaming stream, running bank-full, as is its wont in the early harvest months; the decisive moment when the naked feet of the priests were dipped in the water. What a hush of almost painful expectation would fall on the gazers! Then, with a rush of triumph, the long sentence pours on, like a river escaping from some rocky gorge, and tells the details of the transcendent fact. Looking up stream, the water 'stood'; and, as the flow above went on, it was dammed up, and, as would appear, swept back to a point not now known, but apparently some miles up. Looking down the course, the water flowed naturally to the Dead Sea; and, in effect, the whole bed southwards was quickly left bare, giving room for the advance of the people with wide-extended front, while the priests, with the ark on their shoulders, stood silent in the midst of the bed, between the heaped waters and the hasting host. Verse 17 gives the usual summary sentence, which partly anticipates what is still to follow, but here comes in with special force, as gathering up the whole wonderful scene, and recounting once more, and not without a ring of astonished triumph, how the priests stood firm on dry ground in that strange place, 'until all the nation were passed clean over Jordan'
From verses 7 and 10 we learn the purpose of this miracle as being twofold. It was intended to stamp the seal of God's approbation on Joshua, and to hearten the people by the assurance of God's fighting for them. The leader was thereby put on the level of Moses, the people, on that of the generation before whom the Red Sea had been divided. The parallel with that event is obvious and significant. The miracle which led Israel into the wilderness is repeated as they pass from it. The first stage of their deliverance and the second are begun with analogous displays of divine power. The same arm which cleft the sea is stretched out, after all sins, for the new generation, and 'is not shortened that it cannot save.' God does not disdain to duplicate His wonders, even for very unworthy servants. The unchanging, long-suffering patience, and the unwearied strength to which all generations in succession can turn with confidence, are wonderfully set forth by these two miracles. And though we have passed into the higher stage, where miracles have ceased, the principle which dictated the parallelism still holds good, and we too can look back to all these ancient wonders, and be sure that they are done over and over again according to our needs. 'As we have heard, so have we seen,' might have been Israel's song that day, as it may be ours every day.
The beautiful application made of the parted waters of Jordan in Christian literature, which sees in them the prophecy of conquered death, is perhaps scarcely in accordance with truth, for the divided Jordan was the introduction, not to peace, but to warfare. But it is too deeply impressed on the heart to be lightly put aside, and we may well allow faith and hope to discern in the stream, whose swollen waters shrink backwards as soon as the ark is borne into their turbid and swift current, an emblem of that dark flood that rolled between the host of God and their home, and was dried up as soon as the pierced foot of the Christ touched its cold waters.
'What ailest thee, thou sea, that thou fleest; thou Jordan, that thou turnest back?' Christ has gone up before us. He has shaken His hand over the river, and caused men to go over dry shod.
