Exodus Chapter 12 Verse 7And they shall take of the blood, and strike [it] on the two side posts and on the upper door post of the houses, wherein they shall eat it.

But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that the LORD doth put a difference between the Egyptians and Israel.

And all these thy servants shall come down unto me, and bow down themselves unto me, saying, Get thee out, and all the people that follow thee: and after that I will go out. And he went out from Pharaoh in a great anger.

And the LORD said unto Moses, Pharaoh shall not hearken unto you; that my wonders may be multiplied in the land of Egypt.

And Moses and Aaron did all these wonders before Pharaoh: and the LORD hardened Pharaoh's heart, so that he would not let the children of Israel go out of his land.

And the LORD spake unto Moses and Aaron in the land of Egypt, saying,

This month [shall be] unto you the beginning of months: it [shall be] the first month of the year to you.

Speak ye unto all the congregation of Israel, saying, In the tenth [day] of this month they shall take to them every man a lamb, according to the house of [their] fathers, a lamb for an house:

And if the household be too little for the lamb, let him and his neighbour next unto his house take [it] according to the number of the souls; every man according to his eating shall make your count for the lamb.

Your lamb shall be without blemish, a male of the first year: ye shall take [it] out from the sheep, or from the goats:

And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening.

And they shall eat the flesh in that night, roast with fire, and unleavened bread; [and] with bitter [herbs] they shall eat it.

Eat not of it raw, nor sodden at all with water, but roast [with] fire; his head with his legs, and with the purtenance thereof.

And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire.

And thus shall ye eat it; [with] your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste: it [is] the LORD'S passover.

For I will pass through the land of Egypt this night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I [am] the LORD.

And the blood shall be to you for a token 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.

And this day shall be unto you for a memorial; and ye shall keep it a feast to the LORD throughout your generations; ye shall keep it a feast by an ordinance for ever.

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

And in the first day [there shall be] an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save [that] which every man must eat, that only may be done of you.

And ye shall observe [the feast of] unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.
