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?

δια να ηναι τουτο σημειον μεταξυ σας· ωστε οταν ερωτωσιν οι υιοι σας εις το μελλον λεγοντες, Τι δηλουσιν εις εσας οι λιθοι ουτοι;

That this may be a sign among you, that when your children ask their fathers in time to come, saying, What mean ye by these stones?
