Deuteronomy 11:8-17

Therefore shall ye keep all the commandment which I command thee this day, that ye may be strong, and go in and possess the land, whither ye go over to possess it; and that ye may prolong your days in the land, which Jehovah sware unto your fathers to give unto them and to their seed, a land flowing with milk and honey. For the land, whither thou goest in to possess it, is not as the land of Egypt, from whence ye came out, where thou sowedst thy seed, and wateredst it with thy foot, as a garden of herbs; but the land, whither ye go over to possess it, is a land of hills and valleys, and drinketh water of the rain of heaven, 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. Take heed to yourselves, lest your heart be deceived, and ye turn aside, and serve other gods, and worship them; and the anger of Jehovah be kindled against you, and he shut up the heavens, so that there shall be no rain, and the land shall not yield its fruit; and ye perish quickly from off the good land which Jehovah giveth you.
