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 “No one outside a priest’s family may eat the sacred offerings. Even guests and hired workers in a priest’s home are not allowed to eat them.

11 However, if the priest buys a slave for himself, the slave may eat from the sacred offerings. And if his slaves have children, they also may share his food.

12 If a priest’s daughter marries someone outside the priestly family, she may no longer eat the sacred offerings.

13 But if she becomes a widow or is divorced and has no children to support her, and she returns to live in her father’s home as in her youth, she may eat her father’s food again. Otherwise, no one outside a priest’s family may eat the sacred offerings.

14 “Any such person who eats the sacred offerings without realizing it must pay the priest for the amount eaten, plus an additional 20 percent.
