Matthew Poole and continuators on Leviticus 22:12

12 If the priests daughter also be married unto a stranger , she may not eat of an offering of the holy things.

(i. e.) To one of another family, who is no priest. Yet the priests wife, though of another family, might eat. The reason of which difference is, because the wife passeth into the name, state and priviledges of her husband, from whom the family is denominated and esteemed.
