Deuteronomy 11:10-17

10For 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: 11But the land, whither ye go to possess it, is a land of hills and valleys, and drinketh water of the rain of heaven: 12A land which Yhwh thy God careth for: the eyes of Yhwh thy God are always upon it, from the beginning of the year even unto the end of the year.1

13And it shall come to pass, if ye shall hearken diligently unto my commandments which I command you this day, to love Yhwh 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 grain, and thy wine, and thine oil. 15And I will send grass in thy fields for thy cattle, that thou mayest eat and be full.2 16Take heed to yourselves, that your heart be not deceived, and ye turn aside, and serve other gods, and worship them; 17And then Yhwh's wrath be kindled against you, and he shut up the heaven, that there be no rain, and that the land yield not her fruit; and lest ye perish quickly from off the good land which Yhwh giveth you.
