Deuteronomy 6:1-2

NOW THIS is the instruction, the laws, and the precepts which the Lord your God commanded me to teach you, that you might do them in the land to which you go to possess it, That you may [reverently] fear the Lord your God, you and your son and your son's son, and keep all His statutes and His commandments which I command you all the days of your life, and that your days may be prolonged.
