Deuteronomy 4:39-40

39“So you will know today and take to heart that Adonai, He is God, in the heavens above and on the earth below—there is no other.

40You must keep His statutes and His mitzvot, which I am commanding you today, so that it may go well with you and with your children after you, and so that you may prolong your days in the land that Adonai your God is giving you for all time.”
