No one outside a priest's family may eat the sacred offering, nor may the guest of a priest or his hired hand eat it.

Exodus 12:45
A temporary resident or hired hand shall not eat the Passover.

Exodus 29:33
They must eat those things by which atonement was made for their ordination and consecration. But no outsider may eat them, because these things are sacred.

Leviticus 22:13
But 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.

Numbers 3:10
So you shall appoint Aaron and his sons to carry out the duties of the priesthood; but any outsider who approaches the tabernacle must be put to death."

There shall no stranger eat of the holy thing: a sojourner of the priest, or an hired servant, shall not eat of the holy thing.
