Deuteronomy 11:21

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;

23Then will the LORD drive out all these nations from before you, and ye shall possess greater nations and mightier than yourselves.
