An ox-goad has different laws for its outer and inner parts, [The outer part is] the seven handbreadths from the broad blade and four handbreadths from the point, the words of Rabbi Judah. Rabbi Meir says: it is not to [subject to such distinction], the four and the seven handbreadths were mentioned only in regard to its remnants.

Measures of wine or oil, a fork-ladle, a mustard-strainer and a wine-filter have an outer and inner side, the words of Rabbi Meir. Rabbi Judah says: they do not have. Rabbi Shimon says: they do have, for if their outer parts contracted uncleanness that which is inside remains clean, and immersion is required.

If [in a measure consisting of] a quarter [of a log] and half a quarter [of a log] the quarter measure contracted uncleanness, the half-quarter measure does not become unclean, and if the half-quarter contracted uncleanness the quarter does not become unclean. They argued before Rabbi Akiva: since the half quarter measure is the outer part of the quarter measure, should not the outer side of the vessel whose inner side contracted uncleanness become unclean? He answered them: Are you sure that it belongs to the category [of vessels] that have inner [and outer] parts? Perhaps the quarter is to be regarded as the outer side of the half quarter and, surely, the inner side of a vessel does not become unclean if the outer side contracted uncleanness.

If the [inside of the] quarter contracted uncleanness, the quarter and its outer side are unclean, but the half quarter and its outer side remain clean. If the [inside of the] half quarter contracted uncleanness, the half quarter and its outer side are unclean, but the quarter and its outer side remain clean. If the outer side of the quarter contracted uncleanness,the outer side of the half quarter remains clean, the words of Rabbi Meir. But the sages say: the outer side cannot be divided. When he immerses the vessel, he must immerse the whole thing.

The bases, rims, hangers or handles of vessels that have a receptacle upon which an unclean liquid fell, one dries them and they remain clean. But [if unclean liquid fell] on any part of any other vessel which cannot hold pomegranates (or in which no distinction is made between its outer and inner sides), the whole becomes unclean. If the outer side of a vessel contracted uncleanness from a liquid, only its outer side is unclean but its inner side, rim, hanger and handles remain clean. If its inner side contracted uncleanness the whole is unclean.

All vessels have outer and inner sides and have a part by which they are held. Rabbi Tarfon says: this applies only to a large wooden [kneading] trough. Rabbi Akiva says: it applies to cups. Rabbi Meir says: it applies to unclean and clean hands. Rabbi Yose says: they said this only concerning clean hands.

How so?If one's hands were clean and the outer side of a cup was unclean, one may hold it by its holding-place and need not be concerned lest his hands have contracted uncleanness from the outer side of the cup. If one was drinking from a cup whose outer side was unclean he need not be concerned lest the liquid in his mouth contracted uncleanness from the outer side of the cup and that it then conveyed uncleanness to the cup. If a kettle was boiling one need not be concerned lest liquid should come out from it and touch its outer side and return again within it.

Holy vessels do not have outer and inner sides or a part by which they are held. One may not immerse vessels within one another for sacred use. All vessels become susceptible to uncleanness by intention, but they cannot be rendered insusceptible except by a change-effecting act, for an act annuls an earlier act as well as an earlier intention, but an intention annuls neither an earlier act nor an earlier intention.
