Exodus 12:3-8

³Speak ye to the whole assembly of the children of Israel, and say to them: On the tenth day of this month let every man take a lamb by their families and houses.

⁴But if the number be less than may suffice to eat the lamb, he shall take unto him his neighbour that joineth to his house, according to the number of souls which may be enough to eat the lamb.

⁵And it shall be a lamb without blemish, a male, of one year: according to which rite also you shall take a kid.

⁶And you shall keep it until the fourteenth day of this month: and the whole multitude of the children of Israel shall sacrifice it in the evening.

⁷And they shall take of the blood thereof, and put it upon both the side posts, and on the upper door posts of the houses, wherein they shall eat it.

⁸And they shall eat the flesh that night roasted at the fire, and unleavened bread with wild lettuce.
