[If] the daughter of a Kohen married a Yisrael and afterwards ate terumah, she pays the principal but she does not pay the [additional] fifth, and her death [penalty] is by burning. [If] she was married to any one of the forbidden persons, she pays the principal plus a fifth; and her death [penalty] is by strangulation. [These are the] words of R' Meir. But the Sages say: This one and this one pay the principal and do not pay the [additional] fifth, and their death [penalty] is by burning.
