Leviticus 22:12 Meaning and Commentary

Leviticus 22:12

If the priest's daughter also be [married] to a stranger
Not to an Heathen, but to any Israelite, that is, a common man, or a layman, as the Targums of Onkelos and Jonathan, one that is not a priest; but is married either to a Levite, or an Israelite, as Jarchi: she may not eat of an offering of the holy things;
the heave shoulder or wave breast being removed into another family by marriage, she is not reckoned of her father's family, and so had no more a right to eat of the holy things.

Leviticus 22:12 In-Context

10 And no stranger shall eat the holy things: one that sojourns with a priest, or a hireling, shall not eat the holy things.
11 But if a priest should have a soul purchased for money, he shall eat of his bread; and they that are born in his house, they also shall eat of his bread.
12 And if the daughter of a priest should marry a stranger, she shall not eat of the offerings of the sanctuary.
13 And if the daughter of priest should be a widow, or put away, and have no seed, she shall return to her father's house, as in her youth: she shall eat of her father's bread, but no stranger shall eat of it.
14 And the man who shall ignorantly eat holy things, shall add the fifth part to it, and give the holy thing to the priest.
