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

A chalalah [a woman who had sexual relations with a priest whom she is forbidden to marry because of his priestly status (e.g., she was a divorcee), or the daughter born from such a relationship] may not eat Terumah (the priestly tithe) or the chest and foreleg [of the Peace Offering that is gifted to the priest].

Included in this precept is the prohibition against the daughter of a priest who married a non-priest from partaking of the chest or foreleg—even if she has divorced or is widowed.
