Terumos 6:1 - 6:2

האוכל תרומה שוגג משלם קרן וחומש – as it is written (Leviticus 22:14): “but if a man eats a sacred donation unwittingly, he shall pay the priest for the sacred donation, adding one-fifth of its value.” And the one-fifth is one quarter of what he ate, as for example, if he ate heave-offering that was worth a Denar, he pays a Deinar and one-quarter, which are amidst all, five-fourths Denar, it is found that the principle with its fifth is five, and all the added-fifths mentioned in the Torah are such.

אחד השותה – [who drinks] wine.

ואחד הסך – [who anoints] with oil. For drinking is included within eating, as it is written (Deuteronomy 14:26): “[and spend the money on anything you want -] cattle, sheep, wine, or any other intoxicant,” and it is written afterwards (ibid.,) “and you shall feast there.” And anointing is like drinking, as it is written (Psalms 109:18): “May it enter his body like water, his bones like oil.”

וחומש חומשה – for if he ate heave-offering and paid the principal and added-fifth, and went back and ate the payment of the fifth, he adds a fifth on that same fifth.

אינו משלם תרומה – for the heave-offering is for the Kohen, and the payments of what he ate are an obligation upon hi, and he is not able to pays his obligation from another place.

אלא חולין מתקונים – tha they separated from them heave-offerings and tithes, for the All-Merciful stated (Leviticus 22:14): “He shall pay the priest for the sacred donation,” that things which is appropriate to me holy. And the added fifth also needs to come from designated unconsecrated produce , as it is written (Leviticus 22:14): “adding one-fifth of its value,” teaching that its added fifth is like it.

והן נעשין תרומה – those designated unconsecrated produce.

והתשלומין תרומה – if he went back and inadvertently ate that unconsecrated produce that had been paid, what he goes back and pays in their place, they also become heave-offering.

אינו מוחל – for since the decree of the Biblical verse is that he is liable to pay the appropriate thing to become holy and is not able to exempt himself with money, the matter is not dependent upon the owners.

בת ישראל – [the daughter of an Israelite] who separated heave-offering, but did not give it to the Kohen and inadvertently ate it [herself].

ואח"כ נשאת לכהן – and behold she is worthy to consume heave-offering/Terumah for the wife of a Kohen eats heave-offering/Terumah.

משלמת קרן וחומש לעצמה – behold if that selfsame heave-offering that she ate now in its natural form, she would not be liable to give to a Kohen for she has become a Kohenet through her marriage. Therefore, now, the payments are hers.

משלמת קרן לבעלים – according to the law of steal from one’s colleague, but the added fifth is detained for herself.
