Exodus 12:4

NLT: If a family is too small to eat an entire lamb, let them share the lamb with another family in the neighborhood. Whether or not they share in this way depends on the size of each family and how much they can eat.

GNT: If his family is too small to eat a whole animal, he and his next-door neighbor may share an animal, in proportion to the number of people and the amount that each person can eat.
