Exodus 12:10-20

10And ye shall let none of it remain until the morning; and what remaineth of it until the morning ye shall burn with fire.

11And thus shall ye eat it: your loins shall be girded, your sandals on your feet, and your staff in your hand; and ye shall eat it in haste; it is Jehovah's passover.

12And I will go through the land of Egypt in that night, and smite all the firstborn in the land of Egypt, both man and beast; and against all the 1gods of Egypt I will execute judgment: I am Jehovah.

13And the blood shall be for you as a sign on the houses in which ye are; and when I see the blood, I will pass over you; and the plague shall not be among you for destruction, when I smite the land of Egypt.

14And this day shall be unto you for a memorial; and ye shall celebrate it [as] a feast to Jehovah; throughout your generations [as] an ordinance for ever shall ye celebrate it.

15Seven days shall ye eat unleavened bread: on the very first day ye shall put away leaven out of your houses; for whoever eateth leavened bread from the first day until the seventh day — that soul shall be cut off from Israel.

16And on the first day ye shall have a holy convocation, and on the seventh day a holy convocation: no manner of work shall be done on them, save what is eaten by every person — that only shall be done by you.

17And ye shall keep the [feast of] unleavened [bread]; for in this same day have I brought your hosts out of the land of Egypt; and ye shall keep this day in your generations [as] an ordinance for ever.

18In the first [month], on the fourteenth day of the month, in the evening, ye shall eat unleavened bread until the one and twentieth day of the month in the evening.

19Seven days shall there be no leaven found in your houses; for whoever eateth what is leavened — that soul shall be cut off from the assembly of Israel, whether he be a sojourner, or born in the land.

20Ye shall eat nothing leavened: in all your dwellings shall ye eat unleavened bread.
