13. And this blood shall be to you for a sign upon the houses where ye are; and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.
14. And this day shall be unto you for a memorial; and ye shall keep it as a feast unto the Lord throughout your ages; ye shall keep it a feast by an ordinance forever.
15. Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.
16. And in the first day there shall be a holy convocation, and in the seventh day there shall be a holy convocation to you; no manner of work shall be done in them, except that which every person must eat, that only may be done of you.
17. And ye shall observe the feast of unleavened bread, for in this same day have I brought your hosts out of the land of Egypt; therefore, shall ye observe this day for your ages by an ordinance forever.
18. In the first month, on the fourteenth day of the month in the evening, ye shall eat unleavened bread until the twenty-first day of the month in the evening.
