Joshua 4:21

And he said to the children of Israel, When your children say to their fathers in time to come, What is the reason for these stones?

So that this may be a sign among you; when your children say to you in time to come, What is the reason for these stones?

Let your voice be sounding in songs and melody; let all your thoughts be of the wonder of his works.
