The punishment of the four deaths did not cease - דין ד' מיתות לא בטלו
Summary:
The punishment of דין ד' מיתות generally is according to the sin (but not harsher); however תשובה or a זכות may mitigate or postpone the punishment.
According to Abaye a stranger who ate Terumoh is exempt - זר שאכל תרומה לאביי פטור
Summary:
The payment of תשלומי תרומה, which is for a כפרה and not (merely) monetary compensation to the כהן, is not subject to קלב"מ. The גזה"כ, which suspends the קלב"מ by מעילה, is only regarding מיתה בידי שמים, but not regarding כרת.
If he can disgorge it, let him disgorge it - אי דמצי לאהדורה ניהדרה
Summary:
There seems to be three stages; מצי לאהדורי (where there is no חיוב ממון yet), לא מצי לאהדורי (where there is a חיוב ממון), and בלע לגמרי (at which point there is חיוב מיתה).
And if he cannot disgorge it, why is he liable - ואי דלא מצי לאהדורה אמאי חייב
Summary:
שיטת רש"י: The question of אמאי חייב refers to מיתה since it was forced.
שיטת תוספות: The question is why is there a חיוב ממון , since it is לא מצי לאהדורה it is worthless to the owner.
שיטת הריצב"א: Why is there a חיוב מיתה and why is there a חיוב ממון since he does not want the איסור.
It is applicable only where he can disgorge it with difficulty - לא צריכא דמצי לאהדורה על ידי הדחק
Summary:
The case of קלב"מ by תחב לו בבית הבליעה is when the תרומה was initially worth a פרוטה and now it is worth less than a פרוטה, but since there was a חסר he must pay for the entire הנאה. According to the ריצב"א, since the act of swallowing followed immediately after the thrusting, it is considered באין כאחד and the פטור of קלב"מ applies.
