Exodus 13:7-9 Unleavened cakes shall be eaten seven days; and nothing leavened shall be seen with you, and no yeast should be seen with you within your entire boundary.

CLV⁽ⁱ⁾ ⁷ Unleavened cakes shall be eaten seven days; and nothing leavened shall be seen with you, and no yeast should be seen with you within your entire boundary. ⁸ Then you will tell your son in that day, saying: It is for the sake of this which Yahweh did for me when I went forth from Egypt. ⁹ And you will come to have this as a sign on your hand and as a reminder between your eyes that the law of Yahweh may be in your mouth; for with a steadfast hand Yahweh brought you forth from Egypt.
