הזיז שפניו למטה (the projection from the door frame serving as a shed over the entrance, or a molding projecting from a window-sill serving as a bracket --- the finished side of which faces the ground) – like a tablet/board that projects out from the wall outward and its head is bent to the land to side of the opening. Therefore, its tent combines with the opening and brings the defilement in any amount and it is considered as if it has an opening of a handbreadth, but if the defilement is underneath it, the house is impure, that we see its head bent downward as if it reached the ground and it brings defilement to the side of the house.

וגיזרה – that it faces upward. Its head is bent upward and its tent does not combine with the opening, therefore, it requires an opening of a handbreadth.

וגבלית (a Giblean balcony) – The Tosefta (Tosefta Ohalot, Chapter 14, Halakha 9) explains that it is vessel which sucks from (is girded to the wall on) both sides and left alone (without support) in the middle.

שנים עשר טפחים – for the measurement each נדבך/course of stones or tier/layer is four handbreadths, and a נדבך is a row of the stones of the building.

והעטרות (cornice, molding, wreaths -above the entrance) – stones arranged in a circle that protrude from the wall above from the opening similar to an archway for beauty.

והפתוחים (and the engravings -above the entrance)- that they make from stone on the opening or on the window for beauty, and sometimes they protrude from the window or from the opening a handbreadth or more.

זיז שעל גבי הפתח וכו' – here we are speaking where the opening is concealed. And because of this, we require that the projection will have an opening of a handbreadth. And this is implied in the Tosefta (see Tosefta Ohalot, Chapter 14, Halakha 9).

ושעל גבי החלון רום אצבעיים – that is to say, whether a window whose measure is a height of two fingerbreadths, such as the remnants of the light-hole (i.e., opening in the wall from the start – see Tractate Ohalot, Chapter 13, Mishnah 1) or whether its measurement is as large as the hole made with the [large carpenter’s] borer/drill, as for example, that makes the light-hole at the outset, the projection that on top of both of this is whatever the amount.

ורבי יוסי אומר מלואו (only if its height is of equal measure/of full capacity) – a window whose measure is a height of two fingerbreadths, its projection it’s measure is with two fingerbreadths. But a window whose measurement is as large as the hole made by a borer/drill, its projection we also estimate/assess to be as large as the hole made by a borer/drill. But the Halakha is not according to Rabbi Yossi.

אפילו גבוה מאה אמה – even if the projection, the measurement of its height from the opening is twelve handbreadths, with a reed they were stringent because it is carried. But Rabbi Yohanan ben Nuri holds that one should not be stringent with a reed more than with the wall projection, and higher than twelve handbreadths with an opening of one handbreadth. And the Halakha is according to Rabbi Yohanan ben Nuri.

זיז – which is a handbreadth wide and surrounds all the walls of the house from the outside, and opposite the opening/door extends three fingerbreadths, but on the rest of the opening/door, there is no projection. For if there was an extension opposite the opening/door of a handbreadth, the house would be impure according to the words of everyone.

כלים שתחתיו טמאים – in this Rabbi Yehoshua does not dispute as he disputes in the concluding clause [of the Mishnah], because it is the manner of defilement to depart/go out.

רבי אליעזר מטמא את הבית – because the projection is stringent that it defiles in any amount, it brings defilement to the house with three fingerbreadths.

וכן בחצר שהיא מוקפת אכסדרה – but the covered place in front of the house/parlor extends three finger breadths, [if] defilement is in the house, vessels that are in the parlor are impure. [If] defilement is in the parlor, Rabbi Eliezer declares the house to be impure. But Rabbi Yehoshua declares it to be pure. And the Halakha is according to Rabbi Yehoshua.

שני זיזין זה על גב זה – and they are corresponding this one opposite that one.

יש בהן פותח פתח – that each one of the wall projections – its width is a handbreadth by a handbreadth.

וביניהן פותח טפח – the bottom one is above from the ground a handbreadth and the upper one is a handbreadth above from the lower one.

וטומאה תחתיהן – underneath the bottom one. Everything that is below it is impure and what is above it is pure, for it interposes in the face of the defilement.

ביניהן – if defilement is between the bottom one (i.e., projection) and the upper one, everything that is between them is impure. But what is under the bottom one and that which is above the higher one, is pure, for they interpose.

על גביהן – on top of the upper projection. And what is opposite the defilement until the firmament, is impure. And all the rest is pure.

היה העליון עודף על התחתון וכו' תחתיהן וביניהן טמא – that whether the defilement is under the lower [projection] or whether that the defilement is between them, the very excess that the upper projection is greater than the bottom [projection] by a handbreadth combines the defilement in every place. But what is above the upper [projection] is pure, for it interposes.

על גביהן – on top of the upper [projection].

היה העליון עודף על התחתון וכו' טומאה תחתיהן – that is under the lower [projection].

תחתיהן וביניהן טמא – for that surplus combines/mixes the defilement and brings the defilement to what is below it.

ביניהן – if the defilement is between them or blow on the ground underneath the supplement, that is opposite the excess/surplus but not below the lower [projection].

רבי אליעזר אומר תחתיהן וביניהן טמא – for even though there isn’t a handbreadth in the surplus, it brings the defilement under the lower [projection], since the surplus is over it [as a tent].

ביניהן ותחת המותר טמא – what is between the two projections and what is underneath them on the ground opposite the surplus is impure.

ותחתיהן טהור – what is underneath the lower [projection], for since there isn’t in the surplus a handbreadth, the defilement does not come underneath the lower [projection]. And the Halakha is according to Rabbi Yehoshua.

אין בהן פותח טפח – that the [wall] projection do not have the width of a handbreadth, therefore, whether the defilement is below or whether the defilement is above, it does not interpose at all.

וכן שתי יריעות שהן גבוהות מן הארץ בפותח טפח – and they higher than each other by a handbreadth, and their law is like that of two [wall] projections.
