Oholos 2:2 - 2:3

רביעית דם (a quarter-LOG of blood) – that all of it left [the body] after death.

ורביעית דם תבוסה (a quarter LOG of blood that flows from a person at the time of his death or afterwards – which has the status of a corpse) – that part of a quarter [of a LOG] of blood while living and after death. And further ahead in Chapter 3 [Mishnah 5], it explains this.

תבוסה – it is the language of (Ezekiel 16:6): “[When I passed by you and saw you] wallowing in your blood, [I said to you: [Live in spite of your blood’].” And the quarter [of a LOG] of blood all of which exited [the body] after death, is from the Rabbis, as it is written (Numbers 19:13): “[Whoever touches] a corpse, the body of person who has died.

But [the concept] of דם תבוסה/that part of a quarter [of a LOG] that flows from a person at the time of his death or afterwards. For the Rabbis hold that there is "יש אם למסורת" /the consonantal text of the Torah is authoritative [when looking at Leviticus 21:11): "ועל כל נפשות מת לא יבא"/He shall not go in where there is any dead body,” [the word] נפשת/dead, is written defectively (i.e., without the letter “Vav” In it).

רבי עקיבא אומר משני מתים – one-half of a quarter [of a LOG of blood] from this dead person and one-half of a quarter [of a LOG of blood] from another dead person, defiles in the tent, for he (i.e., Rabbi Akiba) holds, "יש אם למקרא"/the vocalized text of the Torah is authoritative, [as the Biblical verse from Leviticus 21:11) is pronounced: "נפשות מת"/any dead body, implying two souls and one measurement, for since it does not state [in Scripture] "נפשות מתים"/dead bodies. But the Halakha is not according to Rabbi Akiba.

ר' עקיבא אומר כל שהוא – just bones defile with the majority of the number of bones and the majority of the frame, even though one-quarter of a Kab which is the designated measurement for bones, so also, it is defiled if the blood of minor – all of which exited the body, even though it doesn’t have the quarter [of a LOG] which the designated measure for blood.

וחכמים אומרים רביעית – if you were to say that with the bones that it is known that all of them are in front of you, shall you say regarding the blood that I state that there remains a drop of any amount and that not all of it has come out? But the Halakha is according to the Sages.

כזית רמה –[a olive’s bulk of a worm] that was born in the flesh of the corpse.

מטמא כבשרו – that a room that comes out from the corpse even while living, is considered to be like the flesh of a corpse, because, a person while alive is called a worm, as it is written (Job 25:6): “How much less man, a worm, [the Son of man, a maggot].”

וחכמים מטהרים – And the Halakha is according to the Sages.

אפר שרופים – a person that was burned and became ash, and the ash of wood was not combined in it.

שעורו ברובע – [a quarter] of a Kab of ash, defiles.

וחכמים מטהרי – And the Halakha is according to the Sages.

עפר קברות – dirt that the blood and moistness of the corpse is mixed in. And a spoonful of dust and a bit more is impure, because it is impossible to fill a spoon and a bit more so that there would not be in it a spoonful (i.e., two handfuls) of the body of a corpse when its moisture has departed, that it stated above (i.e., in Mishnah 1 of this chapter) that this is impure, But here, it also speaks of a corpse that is buried naked in a marble coffin/bier which has other dirt mixed into it.

ר' שמעון מטהר – But the Halakha is not according to Rabbi Shimon.

אימנו חיבור לטומהא – for if it had overshadowed over part of it, it is not as if it overshadowed over all of it. And similarly, regarding the matter of contact/touching.

עצם שעורה – defiles through contact and through carrying, as it is written (Numbers 19:18): “[A person who is clean shall take hyssop, dip it in the water, and sprinkle on the tent and on all the vessels and people who were there,] or on him who touched/ועל הנגע [the bones or the person who was killed or died naturally or the grave,” but there it does not state, "בעצם אדם"/human bone (as we find in Numbers 19:16). [This comes] to teach about the bone the size of a barleycorn that defiles through contact even though it is not recognized that it of a human being. But in the tent, it is written (Numbers 19:14): “When a person dies in a tent,” and with regard to a bone for the matter of defilement through overshadowing in a tent, we require that it is recognized that it (i.e., the bone) is of a human being, for in another place (Numbers 19:16) it (i.e., the Torah) states, “or human bone”/או-בעצם אדם.

וארץ העמים – Everything that is outside of the Land [of Israel] is called ארץ העמים/the land of the nations [which is ritually impure]. And here we are speaking of a clod/lump of dust that comes from outside the Land which defiles through contact and through carrying but does not defile though overshadowing in a tent. But a person who enters the land of the nations, even if he did not touch nor carry anything, as for example, that he was riding upon a horse, is impure, but on the airspace of the land of the nations they (i.e., the Rabbis) also decreed.

בית הפרס (area in which uncertainty exists concerning the location of a grave or a corpse) – a field in which a grave was plowed and the bones of the corpse were broken and threshed in the dirt of that field. [And the word] פרס from the language of פרוסה/a broken piece (Isaiah 58:7): “It is to share your bread with the hungry.”

כמה חסרון בשדרה (how much is a sufficient lack in the backbone) -that it will not be defiled [through overshadowing] in the tent, but rather through contact and through carrying.

כמלא מקדח (as large as the hole made with the large carpenters’ borer/drill) – as wide as the incision that they make with an awl.

כדי שינטל מן החי וימות – and the Sages estimated the loss as equivalent to a Sela.

בקטן של רופאים – with a small awl that the doctors open up the wounds.

בגדול של לשכה (concerning the large one of the chamber) – that the Sages estimated as an incision like the size of a Pundiyon.
