Exodus 13:8 ASV

⁶  Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to Jehovah.

⁷  Unleavened bread shall be eaten throughout the seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee, in all thy borders.

⁸  And thou shalt tell thy son in that day, saying, It is because of that which Jehovah did for me when I came forth out of Egypt.

⁹  And it shall be for a sign unto thee upon thy hand, and for a memorial between thine eyes, that the law of Jehovah may be in thy mouth: for with a strong hand hath Jehovah brought thee out of Egypt.

¹⁰  Thou shalt therefore keep this ordinance in its season from year to year.
