Deuteronomy 6:6-9 - Exhortation To Teach The Covenant Principles
6 so shall these words which I am commanding thee to-day, be upon thy heart; 7 and thou shalt impress them upon thy sons, and shalt speak of them, - when thou sittest in thy house and when 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 thy hand, - and they shall serve for bands between thine eyes; 9 and thou shalt write them upon the pests of thy house and within thy gates.
