Then ye shall let your children know - The necessity of an early religious education is inculcated through the whole oracles of God. The parents who neglect it have an awful account to give to the Judge of quick and dead.

Then ye shall let your children know,.... The meaning of the erection of these stones, acquaint them with the whole history, the meaning of which they are designed to perpetuate:

saying, Israel came over this Jordan on dry land; and if they should ask how that could possibly be done, or if they did not, they were to inform them by what means it was brought about, as follows.

Then ye shall let your children know, saying, Israel came over this Jordan on dry land.

4:20-24 It is the duty of parents to tell their children betimes of the words and works of God, that they may be trained up in the way they should go. In all the instruction parents give their children, they should teach them to fear God. Serious godliness is the best learning. Are we not called, as much as the Israelites, to praise the loving-kindness of our God? Shall we not raise a pillar to our God, who has brought us through dangers and distresses in so wonderful a way? For hitherto the Lord hath helped us, as much as he did his saints of old. How great the stupidity and ingratitude of men, who perceive not His hand, and will not acknowledge his goodness, in their frequent deliverances!
