Exodus 13:7-10

EJ2000(i) 7 Bread without leaven shall be eaten the seven days; and nothing leavened shall be seen with thee, neither shall there be any leaven in all thy borders. 8 And thou shalt tell thy son in that day, saying, This is done because of that which the LORD did unto me when he brought me out of Egypt. 9 And it shall be for a sign unto thee upon thy hand and for a memorial before thine eyes, that the LORD’s law may be in thy mouth; for with a strong hand the LORD has brought thee out of Egypt. 10 Thou shalt, therefore, keep this ordinance in its season from year to year.
