Exodus 12:4

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

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.

`(And if the household be too few for a lamb, then hath he taken, he and his neighbour who is near unto his house, for the number of persons, each according to his eating ye do count for the lamb,)

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.
