Exodus 12:4
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
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.
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.
