Deuteronomy 4:39-40

39Know therefore this day, and consider it in thy heart, that the LORD he is God in heaven above, and upon the earth beneath: there is none else. 40Thou shalt keep therefore his statutes, and his commandments, which I command thee this day, that it may be well with thee, and with thy children after thee, and that thou mayest prolong thy days upon the earth, which the LORD thy God giveth thee, for ever.
