הָרֶקַע: The Problem — Tumah and the Korban Pesach
To eat the Korban Pesach one must be tahor — but does partially detached flesh on a living person carry tumas meis?
The Animal Question
אֵבָר הַמְדֻלְדָּל בִּבְהֵמָה — טֻמְאַת נְבֵלָה?
Does a limb still attached but dangling from a living animal carry tumah as a neveilah? R. Akiva poses this to his colleagues — they have no direct tradition on it.
The Human Parallel
אֵבָר הַמְדֻלְדָּל בְּאָדָם — טֻמְאַת מֵת?
Does a dangling limb on a living person carry tumah as a meit? Here the colleagues do have a tradition: it is tahor. The Erev Pesach skin sufferers are the proof — their procedure only works if the detached flesh carries no tumas meis.
R. Akiva asks his colleagues: what is the law of a dangling limb on an animal — is it tamei or tahor? They reply: we have no tradition on that case. But we do have a tradition about a dangling limb on a person — and that is tahor. The proof? The skin sufferers of Jerusalem.
הַמַּעֲשֶׂה: The Erev Pesach Procedure
A vivid street-level scene — Jerusalem, Erev Pesach, skin sufferers lining up at the doctor
The Procedure — Step by Step
א
הוֹלְכִין אֵצֶל הָרוֹפֵא עֶרֶב פֶּסַח
Skin sufferers in Jerusalem regularly went to the doctor on Erev Pesach — this was an established custom, not a one-time event.
ב
לַחְתֹּךְ בָּהֶם — לְהַנִּיחַ בָּהֶם כִּשְׂעֹרָה
The doctor cuts the lesion, leaving a barleycorn's worth (k'se'orah) of flesh still attached — just enough to keep it connected to the body.
ג
לִכְרֹךְ בָּהֶם קוֹץ, וְיִמָּשֵׁךְ וְיֵצֵא
A thorn is wrapped around the remaining flesh — and the thorn pulls it free. The lesion is removed without the doctor directly tearing the flesh.
The goal: to be tahor in time to eat the Korban Pesach that night. The elaborate procedure is entirely in service of this obligation.
The Doctor
טָהוֹר
The doctor is tahor — he handled the blood of another person's wound. R. Akiva rules: blood from another person's wound does not convey tumah to the one who touches it.
The Patient
טָהוֹר
The patient is tahor — his own wound-blood does not render him tamei. A person's own dam makkah (wound blood) does not create tumah for himself.
קַל וָחֹמֶר: From the Human Case to the Animal Case
The skin sufferers establish that a dangling human limb has no tumas meis — R. Akiva uses this to reason about the animal case by kal vachomer
The Kal Vachomer Structure
The Proven Case — Human Dangling Limb
אֵבָר הַמְדֻלְדָּל בְּאָדָם — טָהוֹר
A dangling limb on a living person does not carry tumas meis. Proof: the skin sufferers of Jerusalem had flesh cut and pulled free on Erev Pesach — and they went on to eat the Korban Pesach that night, tahor.
If a dangling limb on a person — where tumas meis is a stringent tumah — is nevertheless tahor, then surely a dangling limb on an animal carries no tumah of neveilah either.

רוֹאִין אָנוּ שֶׁהַדְּבָרִים קַל וָחֹמֶר
R. Akiva concludes: we see that these matters follow a kal vachomer. The human case (tumas meis) is the more stringent category — and even there the dangling limb is tahor. The animal case (tumas neveilah) follows all the more so.
הַמַּסְקָנָה — The City on Erev Pesach
This mishnah offers one of the most vivid street-level glimpses of Jerusalem on Erev Pesach in all of rabbinic literature. Skin sufferers lining up at the doctor, thorns and barleycorns, a careful procedure designed to achieve tahara by nightfall — all of it driven by a single goal: לֶאֱכֹל בְּפִסְחֵיהֶן. R. Akiva's question is framed not as abstract halacha but as a real communal practice that "they were accustomed to do." The kal vachomer resolves it elegantly: wound-blood, whether another's or one's own, does not convey tumah — and the city goes home tahor, ready to bring its korban.
