On the subject of purging and washing and whether this applies to kaelim used for kodesh kodshim AND kodeshim kalim or just the former: How can we hold the latter opiniion given noser that would occur?I understand of course the inyan of nosan tam lifgam for issur and heter but if we apply this to kodeshim kalim why not kodesh kedoshim also? Do you we hold that the noser left over in the pot is ain bo mamash?
See Avodah Zarah 76a where the Amora'im discuss this question. The conclusion of Rav Ashi is that in the case of Kodesh, it is Heterah Bala (it absorbed Heter), for it was not yet Nosar at the time it was absorbed. Ramban writes that it does not become Nosar as a Beli'ah. Rashi writes that it is Nosar, but we are lenient and permit Hag'alah alone.
The law of a Chatas is a Chumra of the Torah. Rashi in Avodah Zarah compares it to the Chiyuv of Kibus. See Kereisi (#93) who says that the Chumra is to consider it as Isura Bala, as if it absorbed Isur.
