Deuteronomy 11:13-16

13And it shall come to pass, if ye shall hearken diligently unto my commandments which I command you this day, to love Jehovah your God, and to serve him with all your heart and with all your soul, 14that I will give the rain of your land in its season, the former rain and the latter rain, that thou mayest gather in thy grain, and thy new wine, and thine oil. 15And I will give grass in thy fields for thy cattle, and thou shalt eat and be full. 16Take heed to yourselves, lest your heart be deceived, and ye turn aside, and serve other gods, and worship them;
