Deuteronomy 6:6-9 - Exhortation To Teach The Covenant Principles
6 And these words which I command thee this day, shall be in thine heart. 7 And thou shalt whet them on thy children, and shalt talk of them when thou art at home in thine house and as thou walkest by the way; and when thou liest down and when thou risest up. 8 And thou shalt bind them for a sign upon thine hand. And they shall be papers of remembrance between thine eyes, 9 and shalt write them upon the posts of thy house and upon thy gates.
