Exodus 12:2-13

2This month shall be unto you the beginning of months: it shall be the first month of the year to you.

3Speak unto all the assembly of Israel, saying, On the tenth of this month let them take themselves each a lamb, for a father's house, a lamb for a house.

4And if the household be too small for a lamb, let him and his neighbour next unto his house take [it] according to the number of the souls; each according to [the measure] of his eating shall ye count for the lamb.

5Your lamb shall be without blemish, a yearling male; ye shall take [it] from the sheep, or from the goats.

6And ye shall keep it until the fourteenth day of this month; and the whole congregation of the assembly of Israel shall kill it between the two evenings.

7And they shall take of the blood, and put [it] on the two door-posts and on the lintel of the houses in which they eat it.

8And they shall eat the flesh in that night, roast with fire, and unleavened bread; with bitter [herbs] shall they eat it.

9Ye shall eat none of it raw, nor boiled at all with water, but roast with fire; its head with its legs and with its in-wards.

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.
