He spoke to the children of Israel, saying, When your children shall ask their fathers in time to come, saying, What mean these stones?
      1. They must let their children know that Jordan was driven back before Israel, who went through it upon dry land, and that this was the very place where they passed over. They saw how deep and strong a stream Jordan now was, but the divine power put a stop to it, even when it overflowed all its banks--"and this for you, that live so long after." Note, God's mercies to our ancestors were mercies to us; and we should take all occasions to revive the remembrance of the great things God did for our fathers in the days of old. The place thus marked would be a memorandum to them: Israel came over this Jordan. A local memory would be of use to them, and the sight of the place remind them of that which was done there; and not only the inhabitants of that country, but strangers and travellers, would look upon these stones and receive instruction. Many, upon the sight of the stones, would go to their Bibles, and there read the history of this wondrous work; and some perhaps, upon reading the history, though living at a distance, would have the curiosity to go and see the stones.
