Exodus 13:6-10 Seven days shalt thou eat unleavened bread, and in the seventh day shall be a feast to the LORD.

Webster⁽ⁱ⁾ ⁶ Seven days shalt thou eat unleavened bread, and in the seventh day shall be a feast to the LORD. ⁷ Unleavened bread shall be eaten seven days: and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy quarters. ⁸ And thou shalt show thy son in that day, saying, This is done because of that which the LORD did to me when I came forth out of Egypt. ⁹ And it shall be for a sign to thee upon thy hand, and for a memorial between thy eyes; that the LORD'S law may be in thy mouth: for with a strong hand hath the LORD brought thee out of Egypt. ¹⁰ Thou shalt therefore keep this ordinance in its season from year to year.
