Devarim 6:7-9

Orthodox Jewish Bible

⁷ And thou shalt teach them diligently unto thy banim, and shalt talk of them when thou sittest in thine bais, and when thou walkest by the way, and when thou liest down, and when thou risest up.

⁸ And thou shalt bind them for an ot upon thine hand, and they shall be as totafos (ornaments [Shemot 13:16, Shabbos 57a]) between thine eyes.

⁹ And thou shalt write them upon the mezuzot of thy bais, and on thy she’arim.
