Deuteronomy 4:39, 40
Know therefore this day and take to heart that the LORD is God in heaven above and on the earth below; there is no other. / Keep His statutes and commandments, which I am giving you today, so that you and your children after you may prosper, and that you may live long in the land that the LORD your God is giving you for all time.
