Deuteronomy 6:6-9

⁶And these words, which I command thee this day, shall be in thine heart: ⁷And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up. ⁸And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes. ⁹And thou shalt write them upon the posts of thy house, and on thy gates.
