And now, please swear [an oath] to me by the Lord, since I have shown you kindness, that you also will show kindness to my father’s household (family), and give me a pledge of truth and faithfulness,

so that this may be a sign among you; when your children ask later, ‘What do these stones mean to you?’

Then you will say to them, Because the waters of Jordan were cut off before the ark of the Lord's agreement; when it went over Jordan the waters of Jordan were cut off: and these stones will be a sign for the children of Israel, keeping it in their memory for ever.
