Leviticus 22:10-13

10No one outside a priest’s family may eat the sacred offering, nor may the guest of a priest or his hired hand eat it. 11But if a priest buys a slave with his own money, or if a slave is born in his household, that slave may eat his food.

12If the priest’s daughter is married to a man other than a priest, she is not to eat of the sacred contributions. 13But if a priest’s daughter with no children becomes widowed or divorced and returns to her father’s house, she may share her father’s food as in her youth. But no outsider may share it.
