Exodus 12:3-5

Darby Translation

³ Speak 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.

⁴ And 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.

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