Deuteronomy 4:39-40

39Know therefore this day, and consider it in thine heart, that Yhwh 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 go well with thee, and with thy children after thee, and that thou mayest prolong thy days upon the earth, which Yhwh thy God giveth thee, for ever.
