'Outsider' in the Bible

‘No layman [that is, someone outside of Aaron’s family] is to eat the holy gift [which has been offered to God]; a foreigner residing with the priest or a hired man shall not eat the holy thing.

If a priest’s daughter is married to a layman [one not part of the priestly tribe], she shall not eat the offering of the holy things.

But if the priest’s daughter becomes widowed or divorced, has no children, and returns to her father’s house as in her youth, she may share her father’s food. But no outsider may share it.
