Deuteronomy 6:5-9

5And thou shalt love the LORD thy God with all thy heart, and with all thy soul, and with all thy might. 6And these words, which I command thee this day, shall be in thy heart: 7And thou shalt teach them diligently to thy children, and shalt talk 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.1 8And thou shalt bind them for a sign upon thy hand, and they shall be as frontlets between thy eyes. 9And thou shalt write them upon the posts of thy house, and on thy gates.
