Exodus 13:7-10

ASV(i) 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.
