Mishnayos Oholos Perek 18 Mishnah 1

כסאה וכסאתים חותמות – of plaster. And this fact brings Rabbi Yehuda to the assistance of the Rabbis that they didn’t worry about a Se’ah or two Se’ah from the dirt that comes from outside the Land of Israel, for since there wasn’t the seal of one of them on its own like the seal of the leather bags. And the Halakha is according to the Sages.

כיצד בוצרים בית הפרס (how do they cut grapes in an area in which uncertainty exists concerning the location of a grave or a corpse or crushed bones carried over it from a ploughed grave)- so that the grapes that grew in it would be ritually pure.

מזין על האדם ועל הכלים – on the third day [they would sprinkle].

ושונין – on the seventh day [they repeat it].

ומוציאין חוץ לבית הפרס – and even though that one cuts grapes for the vat for wine-pressing are fit for receiving Levitical uncleanness and this is one of eighteen matters that they decreed on the day [that Rabban Gamaliel was deposed as head of the Sanhedrin (see Tractate Berakhot 28a)], these words [refer to] defilement according to the Torah, but concerning the defilement of the a field where uncertainty exists concerning the location of a grave or corpse or crushed bones carried over it from a ploughed grave is Rabbinic, and we don’t consider it a fitness to become unclean. And because of this, it (i.e., the Mishnah) took [the term] and taught: “they sprinkle on the man and on the vessels [and repeat the process],” in order that they would be pure from defilement according the Torah (see Numbers 19:19, and even though they go back and become defiled in the field declared unclean on account of crushed bones carried over from a ploughed grave at the time of the harvesting of grapes, further, the grapes are not defiled through their contract because of the defilement of the field declared unclean on account of crushed bones carried over from a ploughed grave all the while that they did not have a complete fitness to become unclean.

ואחרים – who did not enter into the field declared unclean on account of crushed bones carried over from a ploughed grave.

מקבלין – from those who cut/harvest the grapes.

ומוליכין לגת – in other vessels. But those who cut/harvest the grapes do not bring them to the vat for wine-pressing, because the vat is filled with liquids and they are pronounced fit [for Levitical uncleanness] for a complete fitness.

ואם נגעו אלו באלו – those who cut/harvest the grapes came in contact with/touched the others who receive [the grapes].

טמאים – those who receive [the grapes] and they all of the grapes. For a person that is defiled in a field declared unclean on account of crushed bones carried over from a ploughed grave become a primary source of ritual defilement/ אב הטומאהand it defiles people and vessels [according to the School of Hillel].

בית שמאי אומרים אוחז את המגל – that they (i.e., the School of Shammai) holds that the person who harvests [grapes] in the vat becomes fit for Levitical uncleanness even for the defilement of a field declared unclean on account of crushed bones carried over from a ploughed grave, and because of this, he must hold on to a sickle wrapped in a fibrous substance/bast of a palm tree when he harvests that does not receive defilement.

או בוצר בצור (or he harvests with a flint) – and it is a sharp stone that is not a vessel.

ונותן לתוך הכפישה (places it into an inverted vessel/a vessel divided into two compartments by the bottom between) – a large vessel that one harvests olives in, that it doesn’t receive ritual defilement.
