Mishnayos Oholos Perek 2 Mishnah 2

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.
