Deuteronomy 11:13-28

13And it shall come to pass, if ye shall hearken diligently to 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 its due season, the former rain and the latter rain, that thou mayest gather in thy grain, and thy wine, and thy oil. 15And I will give grass in thy fields for thy cattle, that thou mayest eat and be full.1 16Take heed to yourselves, that your heart be not deceived, and ye turn aside, and serve other gods, and worship them; 17And then the LORD’S wrath shall be kindled against you, and he shall shut up the heaven, that there shall be no rain, and the land shall not yield its fruit; and lest ye perish quickly from off the good land which the LORD giveth you.

18Therefore shall ye lay up these my words in your heart and in your soul, and bind them for a sign upon your hand, that they may be as frontlets between your eyes. 19And ye shall teach them to your children, speaking of them when thou sittest in thy house, and when thou walkest by the way, when thou liest down, and when thou risest up. 20And thou shalt write them upon the door posts of thy house, and upon thy gates: 21That your days may be multiplied, and the days of your children, in the land which the LORD swore to your fathers to give to them, as the days of heaven upon the earth. 22For if ye shall diligently keep all these commandments which I command you, to do them, to love the LORD your God, to walk in all his ways, and to cleave to him; 23Then will the LORD drive out all these nations from before you, and ye shall possess greater nations and mightier than yourselves. 24Every place on which the soles of your feet shall tread shall be yours: from the wilderness and Lebanon, from the river, the river Euphrates, even to the uttermost sea shall your border be. 25There shall no man be able to stand before you: for the LORD your God shall lay the fear of you and the dread of you upon all the land that ye shall tread upon, as he hath said to you.

26Behold, I set before you this day a blessing and a curse; 27A blessing, if ye obey the commandments of the LORD your God, which I command you this day: 28And a curse, if ye will not obey the commandments of the LORD your God, but turn aside from the way which I command you this day, to go after other gods, which ye have not known.
