Joshua 4:23

For the Lord your God dried up the waters of Jordan from before you, until ye were passed over,.... As this is supposed to be said in future time, and to persons who were not upon the spot when this was done, and so entirely ignorant of the affair; it is not to be understood of them personally, but of the same people they were of, the people of Israel in former times, of their ancestors, and of them in them; the benefits of which they enjoyed by possessing the land of Canaan their fathers were at this time introduced into:

as the Lord your God did to the Red sea, which he dried up from before us, until we were gone over; for though the generation of men, for the most part, was dead, that passed through the Red sea; yet as Joshua himself, and Caleb and Eleazar, and it may be some others that were not among the murmurers, were still living, for whom that miracle was wrought, this way of speaking is very properly made use of; and especially when it is observed, that there were many of the present generation then young, which passed over, and even those unborn were in and represented by their ancestors, and who enjoyed the advantages of that wonderful mercy; so these two strange events are joined together, as instances of divine power and goodness, in Psalms 114:3.
