Deuteronomy 11:14

12A land which the LORD thy God careth for: the eyes of the LORD thy God are always upon it, from the beginning of the year even unto the end of the year.

13And 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,

14That I will give you the rain of your land in his due season, the first rain and the latter rain, that thou mayest gather in thy corn, and thy wine, and thine oil.

15And I will send grass in thy fields for thy cattle, that thou mayest eat and be full.

16Take heed to yourselves, that your heart be not deceived, and ye turn aside, and serve other gods, and worship them;
