— He holds that a zab lacking atonement is as a zab. Now, whether a zab lacking atonement is as a zab, is dependent on Tannaim. For it was taught: If an onen or one lacking atonement burns it, it is fit. Joseph the Babylonian said: If an onen [burns it], it is fit, [but] if one who lacks atonement burns it, it is unfit. Now surely they disagree in this: one Master holds that a zab lacking atonement is as a zab, while the other Master holds that he is not as a zab! — No. All agree that he is as a zab, but here they disagree in the following: For it is written, And the clean person shall sprinkle upon the unclean, whence it follows that he is unclean, thus teaching that a tebul yom is fit [to officiate] at the [red] heifer. Now, one Master holds: This applies to every form of uncleanness mentioned in the Torah; while the other Master holds that it applies to the uncleanness dealt with in this chapter only. Therefore an onen and a tebul yom rendered [originally] unclean through a [dead] reptile, who are less stringent, are derived a minori from a tebul yom rendered [originally] unclean through a dead body. But a zab who lacks atonement is not [thus derived], since he is more stringent, as his uncleanness proceeds from his own body. ONE LACKING THE [PRIESTLY] VESTMENTS. Whence do we know it? — Said R. Abbahu in R. Johanan's name, and some derive ultimately [the teaching] from R. Eleazar the son of R. Simeon: Because Scripture saith, And thou shalt gird them with girdles, Aaron and his sons, and bind head-tires on them; and they shall have the priesthood by a perpetual statute: When wearing their [appointed] garments, they are invested with their priesthood; when not wearing their garments, they are not invested with their priesthood. Now, is this derived from the verse quoted? Surely it is derived from elsewhere? For it was taught: How do we know that if one who had drank wine officiates, he profanes [the sacrifices]? Because it is written, Drink no wine nor strong wine....that ye may put difference between the holy and the profane. How do we know [the same of] one who lacks [priestly] vestments and [of] one who had not washed his hands and feet?ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡ
