Leviticus 22:2-3, 11-13

“Tell Aaron and his sons: ‘The people of Israel will give offerings to me. These offerings are holy, and they are mine, so you must respect them to show that you respect my holy name. I am the LORD.’ Say to them: ‘If any one of your descendants from now on is unclean and comes near the offerings that the Israelites made holy for me, that person must be cut off from appearing before me. I am the LORD.

But if the priest buys a slave with his own money, that slave may eat the holy offerings; slaves who were born in his house may also eat his food. If a priest’s daughter marries a person who is not a priest, she must not eat any of the holy offerings. But if the priest’s daughter becomes widowed or divorced, with no children to support her, and if she goes back to her father’s house where she lived as a child, she may eat some of her father’s food. But only people from a priest’s family may eat this food.
