Parashas Kedoshim · Passuk 19:08
Chabad.org — English translation + Rashi
Torah Temimah · Kerisos 5a.
English: It says here “for he has profaned the holy of Hashem” and there “you shall burn the remainder in fire, for it is holy” — just as “holy” there refers to nosar, so “holy” here refers to nosar proper.
This verse returns to true nosar
Although the preceding verse addressed pigul of place, this verse reverts to ordinary leftover (nosar) and its kareis penalty.
