Deuteronomy 11:18

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;

17And then the Lord’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 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 your children, speaking of them when thou sittest in thine 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 thine house, and upon thy gates:

21That your days may be multiplied, and the days of your children, in the land which the Lord sware unto your fathers to give 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 unto him;
