Exodus Chapter 12 Verse 1And the LORD spake unto Moses and Aaron in the land of Egypt, saying,

And the LORD said unto Moses, Yet will I bring one plague [more] upon Pharaoh, and upon Egypt; afterwards he will let you go hence: when he shall let [you] go, he shall surely thrust you out hence altogether.

Speak now in the ears of the people, and let every man borrow of his neighbour, and every woman of her neighbour, jewels of silver, and jewels of gold.

And the LORD gave the people favour in the sight of the Egyptians. Moreover the man Moses [was] very great in the land of Egypt, in the sight of Pharaoh's servants, and in the sight of the people.

And Moses said, Thus saith the LORD, About midnight will I go out into the midst of Egypt:

And all the firstborn in the land of Egypt shall die, from the firstborn of Pharaoh that sitteth upon his throne, even unto the firstborn of the maidservant that [is] behind the mill; and all the firstborn of beasts.

And there shall be a great cry throughout all the land of Egypt, such as there was none like it, nor shall be like it any more.

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.

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 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.

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.
