Leviticus 22:12 And if a priest's daughter is married to a common man, she shall not eat of that which is set apart of the holy [foods]"

The Torah gives many laws specifically to the priests.

These laws instruct them how to conduct themselves, whom they may marry, what they must wear, and how they offer sacrifices.

When a priest marries a woman forbidden to him by Torah Law, the woman is considered a "Chalalah."

She is not allowed to eat from sacrificial meat that a priest is usually entitled to.

This Negative Mitzvah also prohibits the daughter of a priest who married a non-priest from eating Terumah as long as she is married to this man or any of her children are alive.
