Kerisos 3:7 - 3:8

באיטליס – a marketplace where they sell meat there.

של אמאום – the name of a city.

הבא על אחותו וכו' – this is what he said: he who has sexual relations with his sister who is the sister of of his father and the sister of his mother, and we have found such a case, as, for example, when Reuven had sexual relations with his mother and fathered from her two daughters and then he returned and had sexual relations with one of these daughters and from her fathered a so, and the son had sexual relations with his sister, who is the sister of his father and the sister of his mother.

וחומר – And what if a person had sexual intercourse with five wives who are menstruating women which are one category (Leviticus 18:19): “Do not come near a woman during her period of uncleanness,” he would be liable for each and every one. A person who has sexual relations with his siter, who is the sister of his father and the sister of his mother, which are three categories, meaning to say, three negative commandments that are divided, is it not the case that he should be liable for each and every one? But this a fortiori is refuted/raises an objection, for how can five women who are menstruating be separate/distinct bodies? But the reason, is because as Scripture states (Leviticus 20:17): “He has uncovered the nakedness of his sister, etc.,” and it is an extra verse, for at the beginning of the verse, it is written “If a man marries his sister….so that he sees her nakedness, etc.” Why should he review further “that he has uncovered his sister’s nakedness,” but rather to teach about his sister who is the father’s sister and his mother’s sister, who is liable for each and every one.

אבר המדולדל בבהמה – most of it is detached and part of it is interwoven.

מהו – that he should become defiled because of [the prohibition of] a limb from a living animal, as if it was detached completely, but we hold in [Tractate Hullin, Chapter 9, Mishnah 8] “The Flesh and the Juice,” that a limb from a living animal defiles like a carrion. But a limb that is detached completely from a human being completely defiles like the dead person.

באבר המדולדל באדם – that it is partly interwoven, it is ritually pure.

מוכי שחין (afflicted with boils) - that their limbs are falling.

וחותכה – not because of ritual purity, for before this, it is also ritually pure, but rather so that it is not detestable on the Festival with a dangling limb.

שמניח בו כשערה – but doesn’t cut it off completely, so as to not defile the person who cuts it (i.e., the doctor) when he touches it at the time of its separation.

ותוחבו – to the limb.

בסירה – with a thorn that is attached the ground.

והוא – the sick person.

נמשך – and the limb is torn away on its own, and the sick person is not ritually impure because he pulls himself with strength at one clip and the limb is detached from im with power and there is no contact at the time of separation.

שהדברים קל וחומר – for just as a person is susceptible to ritual defilement while alive, the dangling limb from him is ritually pure, an animal which is not susceptible to ritual impurity while alive, is it not the case that the limb that is dangling from it is ritually pure?
