Psalms 144:4

And it shall come to pass, when your children shall say unto you, What mean ye by this service?

And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand the LORD brought us out from Egypt, from the house of bondage:

And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.

And he spake unto the children of Israel, saying, When your children shall ask their fathers in time to come, saying, What mean these stones? Then ye shall let your children know, saying, Israel came over this Jordan on dry land. For the LORD your God dried up the waters of Jordan from before you, until ye were passed over, as the LORD your God did to the Red sea, which he dried up from before us, until we were gone over: That all the people of the earth might know the hand of the LORD, that it is mighty: that ye might fear the LORD your God for ever.

We have heard with our ears, O God, our fathers have told us, what work thou didst in their days, in the times of old.

Now also when I am old and greyheaded, O God, forsake me not; until I have shewed thy strength unto this generation, and thy power to every one that is to come.

Which we have heard and known, and our fathers have told us. We will not hide them from their children, shewing to the generation to come the praises of the LORD, and his strength, and his wonderful works that he hath done. For he established a testimony in Jacob, and appointed a law in Israel, which he commanded our fathers, that they should make them known to their children: That the generation to come might know them, even the children which should be born; who should arise and declare them to their children: That they might set their hope in God, and not forget the works of God, but keep his commandments:
