that thou mightest fear Jehovah thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son’s son, all the days of thy life; and that thy days may be prolonged.

So that living in the fear of the Lord your God, you may keep all his laws and his orders, which I give you: you and your son and your son's son, all the days of your life; and so that your life may be long.

δια να φοβησαι Κυριον τον Θεον σου, ωστε να φυλαττης παντα τα διαταγματα αυτου και τας εντολας αυτου, τας οποιας εγω σε προσταζω, συ και ο υιος σου και ο υιος του υιου σου, πασας τας ημερας της ζωης σου· και δια να μακροημερευσης.

That thou mightest fear the Lord thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son’s son, all the days of thy life; and that thy days may be prolonged.
