Shemot 13:8-10

Orthodox Jewish Bible

⁸ And thou shalt show thy ben in that day, saying, This is because of what Hashem did for me when I came forth out of Mitzrayim.

⁹ And it shall be for an ot (sign) unto thee upon thine yad, and for a zikaron (reminder) between thine eyes, in order that the torat Hashem may be in thy mouth; because with a yad chazakah hath Hashem brought thee out of Mitzrayim.

¹⁰ Thou shalt therefore be shomer over this chukkah in its mo’ed (season, fixed time) perpetually.
