Deuteronomy 11:8-17

¶ Keep, therefore, all the commandments which I command you this day that ye may be strong and enter in and inherit the land, into which ye go to inherit it and that ye may prolong your days in the land, which the LORD swore unto your fathers to give unto them and to their seed, a land that flows with milk and honey. For the land, into which thou goest to inherit it, is not as the land of Egypt, from which ye came out, where thou didst sow thy seed and water it with thy foot, as a garden of herbs. The land, into which ye go to inherit it, is a land of mountains and valleys and drinks water of the rain of heaven, a land which the LORD thy God procures; the eyes of the thy God procures; the eyes of the LORD 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 the LORD your God and to serve him with all your heart and with all your soul that I will give you the rain of your land in its due season, the early rain and the latter rain, and thou shalt gather in thy grain and thy wine and thine oil. And I will send grass in thy fields for thy beasts, and thou shalt eat and be full. Keep yourselves, therefore, that your heart not be deceived and ye turn aside and serve other gods and worship them; and then the LORD’s wrath be kindled against you and he shut up the heavens, that there be no rain and that the land yield not her fruit, and lest ye perish quickly from off the good land which the LORD gives you.
