Exodus 13:7-9

Darby Translation

⁷ Unleavened bread shall be eaten the seven days; and leavened bread shall not be seen with thee, neither shall there be leaven seen with thee in all thy borders.

⁸ And thou shalt inform thy son in that day, saying, It is because of what Jehovah did to me when I came out of Egypt.

⁹ And it shall be for a sign to thee on thy hand, and for a memorial between thine eyes, that the law of Jehovah may be in thy mouth; for with a powerful hand hath Jehovah brought thee out of Egypt.
