Exodus 13:7-9

Leeser(i) 7 Unleavened bread shall be eaten these seven days; and there shall not be seen with thee any leavened bread, neither shall there be seen with thee any leaven in all thy boundaries. 8 And thou shalt tell thy son on that day, saying, This is done for the sake of that which the Lord did unto me when I came forth out of Egypt. 9 And it shall be unto thee for a sign upon thy hand, and for a memorial between thy eyes, in order that the law of the Lord may be in thy mouth; for with a strong hand hath the Lord brought thee forth out of Egypt.
