Exodus 12:4

If the household is too small for a whole lamb, they are to share with the nearest neighbor based on the number of people, and apportion the lamb accordingly.

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.

and if the household is too little for a lamb, then he and his neighbor next to his house shall take one according to the number of the souls. You shall make your count for the lamb according to what everyone can eat.

and if the household be too little for a lamb, then shall he and his neighbor next unto his house take one according to the number of the souls; according to every man’s eating ye shall make your count for the lamb.
