Deuteronomy 11:13-14

ERV(i) 13 And it shall come to pass, if ye shall hearken diligently unto my commandments which I command you this day, to love the LORD your God, and to serve him with all your heart and with all your soul, 14 that I will give the rain of your land in its season, the former rain and the latter rain, that thou mayest gather in thy corn, and thy wine, and thine oil.
