(Mishnah): A Petzu'a Daka is one whose Beitzim were crushed, even one of them;

A Krus Shafchah is one whose Ever was cut. If even a hair's width remains from the crown, he is permitted.

A Petzu'a Daka or Krus Shofchah is permitted to a convert or freed slave; he is forbidden only to Kehal (Yisraelim) - "Lo Yavo Petzu'a Daka u'Chrus Shafchah bi'Kehal Hash-m."

(Gemara): [Had the Torah said only] Petzu'a, I would have said that this is [one with any crushed limb, even] his eye. It says [next to this Krus] Shafchah [to teach that Petzu'a applies to a limb next to] what spills.

Question: If it is Petzu'a next to what spills, perhaps it is the eye, which is next to the nose!

Answer: It says "Daka" - [the limb] that comes between his thighs (and is crushed);

(R. Chagai, in front of R. Yosi): There is no limb in man, when he sits (squats), lower than his Beitzim (testicles).

Support (R. Yosi bei R. Bun): This is correct! In all other [Pesulei Kahal], the Torah wrote [how many] generations [are forbidden], except for this, for he does not father children.

This is not only when [his Beitzim] were crushed. Rather, it is even if they dissolved, or dried, or even if [any amount] is missing (was cut off).

(Beraisa - R. Yishmael beno Shel R. Yochanan ben Brokah): I heard in Kerem b'Yavneh that anyone who has only one Beitzah cannot father children; he is [like] a Seris Chamah (the Torah permits him).

(R. Yosi): I heard that the Halachah follows R. Yishmael ben R. Yochanan ben Brokah, and I do not know from whom I heard.

(R. Imi): R. Yosi did not hear this from a small person (rather, from a great Chacham; one may rely on him).

(Shmuel): If someone with one Beitzah will come in front of me, I will be Machshir him [to marry a Bas Yisrael].

(Rav Chunah): He holds like R. Yishmael beno Shel R. Yochanan.

(R. Yudan bar Chanin): [Shmuel is Machshir] only if he has the right [Beitzah].

A case came in front of R. Imi. (A woman asked if she may marry a man with only one Beitzah.) He told her, you are permitted to him - but know that he cannot father children.

R. Ze'ira praised [his answer] - 'he established the matter in its clarity' (R. Yishmael said that he is a Seris Chamah to teach that the Torah permits him, but he cannot father children.)

Petzu'a [Daka] - some teach that [if this occurred] through man, he is Pasul; bi'Ydei Shamayim, he is Kosher. Some teach that whether through man or bi'Ydei Shamayim, he is Pasul.

Assumption: The one who says that through man, he is Pasul; bi'Ydei Shamayim, he is Kosher - this is R. Yishmael beno Shel R. Yochanan ben Brokah. The one who says that whether through man, or bi'Ydei Shamayim, he is Pasul - this is Rabanan.

Rebuttal (Rav Acha bar Yakov): Both of them are like Rabanan;

The one who says that through man, he is Pasul; bi'Ydei Shamayim, he is Kosher - he learns from Mamzer. It says "Lo Yavo Mamzer", and it says "Lo Yavo Petzu'a Daka." Just like Mamzer is through man, also Petzu'a Daka is through man.

Question: The one who says that whether through man or bi'Ydei Shamayim, he is Pasul - what is his source?

Answer #1 (R. Mana): He learns from here - "Lo Yavo Petzu'a Daka... l'Olam" (in any case).

Answer #2 (R. Yosi bei R. Bun): Also he learns from Mamzer. It says "Lo Yavo Mamzer", and it says "Lo Yavo Petzu'a Daka." Just like Mamzer is bi'Ydei Shamayim, also Petzu'a Daka is bi'Ydei Shamayim.

Question: Is Mamzer bi'Ydei Shamayim?! (He resulted from Bi'as Isur!)

Answer: His formation is bi'Ydei Shamayim.

If sores came on his Beitzim, and he scratches or cuts, this is bi'Ydei Adam like bi'Ydei Shamayim (since the initial cause was bi'Ydei Shamayim. Only in such a case Rabanan disqualify bi'Ydei Shamayim. We explained this like OHR SOMAYACH, Isurei Bi'ah16:7.)

Krus Shafchah - any case in which the Ever was cut and the crown remained, even like a thread, he is Kosher.

(R. Yosi citing R. Chaninah): [The remnant must be] on the top of the crown [towards the body].

(R. Chiyah citing R. Chaninah): [He is Kosher even if the remnant is] on the bottom of the crown [towards the ground].

(R. Yehoshua ben Levi): [It is even] on the bottom of the crown.

There (in Bavel) they say that if [the Ever] is grooved like a gutter pipe, he is Kosher.

(R. Heila citing R. Yochanan): If [the edge is cut on a slant] like a quill, he is Kosher. If it is like an inverted quill (the edge faces down) he is Pasul.

If it is punctured from the inside, he is Pasul; from the outside, he is Kosher.

(R. Ba citing Rav Yehudah): 'Inside' is from the crown and inside [towards the body]. 'Outside' is from the crown and outside.

If it is punctured [from the inside], he is Pasul. If it was sealed, he is Kosher;

If it is punctured, he is Pasul, for [the semen] spills (through the hole, and does not shoot out of the Ever, so it cannot impregnate). If it was sealed, he is Kosher, for he can father children. This is a Pesul that returns to be Kosher.

(Beraisa): The only difference between Petzu'a Daka and Krus Shafchah (regarding a hole) is based on a cure. A Petzu'a Daka can return [to be Kosher]; a Krus Shafchah cannot return.

Question: How does he do [to seal the hole]?

Answer (R. Yakov bar Acha citing Rav Yehudah): He brings ants [to the hole], and they bite, and he cuts [the bodies and leaves the heads in the hole. They decay, and flesh grows to seal the hole.]

(R. Chilkiyah citing R. Simon citing R. Yehoshua ben Levi): (Our Mishnah permits a Petzu'a Daka to a convert.) This is only for a Petzu'a Daka Yisrael, but not for a Petzu'a Daka Kohen (he is forbidden to a convert).
