Deuteronomy 6:6-9 - Exhortation To Teach The Covenant Principles
6 And these words, which I command thee this day, shall be upon thy heart, 7 and thou shalt repeat them diligently unto thy sons and shalt talk of them being in thy house and walking by the way, lying down in bed, and rising up; 8 and thou shalt bind them for a sign upon thy hand, and they shall be as frontlets between thy eyes; 9 and thou shalt write them upon the posts of thy house and on thy gates.
