But you can refute it thus, and you can refute it thus; [therefore] let each one remain in its place. TEBUL YOM. Whence do we know it? — For it was taught, R. Simai said: Where is the allusion that if a tebul yom officiates he profanes [the sacrifice]? In the text , They [the priests] shall be holy . . and not profane: since this cannot refer to an unclean [priest], for [his prohibition] is deduced from, That they separate themselves, apply it to a tebul yom. Say, apply it to the making of a baldness and the shaving off of the corners of the beard? — Since a tebul yom is liable to death for officiating (and how do we know that? because we deduce [similarity of law] from the use of ‘profanation’ here and in the case of terumah.) [it follows that] he who is unfit [to partake of] terumah profanes the service [of sacrifice], whereas he who is not unfit [to partake of] terumah does not profane the service. Rabbah said:Why must the Divine Law enumerate an unclean priest, a tebul yom, and one who lacks atonement? — They are all necessary. For had the Divine Law written [the law for] an unclean priest [only, I would say that he disqualifies the sacrifice] because he defiles. [If the law were written] with reference to a tebul yom, one who lacks atonement could not be derived from it, seeing that [the former] is disqualified [to partake] of terumah. [If it were written] with reference to one who lacks atonement, a tebul yom could not be learnt from it, seeing that [the former] lacks a [positive] act . Now[one]cannot be derived from one [other], [but] let one be derived from two? — In which should the Divine Law not write [this ruling]? Should it not write [it] with respect to one who lacks atonement, so that it might be inferred from the others, [it might be argued]: as for the others, [their peculiar feature is] that they are disqualified [to partake of] terumah. Rather, let not the Divine Law write it of a tebul yom, which could be inferred from the others. For how will you refute [the analogy]: as for these others, [the reason is that] they are wanting in a [positive] act? [This would be no refutation] for after all, its uncleanness is but slight!15ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒ
