Deuteronomy 11:12-15

a land which Jehovah thy God careth for: the eyes of Jehovah thy God are always upon it, from the beginning of the year even unto the end of the year. And 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, 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 grain, and thy new wine, and thine oil. And I will give grass in thy fields for thy cattle, and thou shalt eat and be full.
