(Mishnah): A [partial] brother from any place (even through an Aveirah) obligates his brother's wife [to do Yibum or Chalitzah]. He is like a brother in every respect;

The only exceptions are a brother from a slave or Nochris.

(Mishnah): A son from any place (even through an Aveirah) exempts his father's wife from Yibum and Chalitzah. He is liable for striking or cursing his father. He is like a son in every respect;

The only exceptions are a son from a slave or Nochris.

(Gemara - R. Avin) Question: Is he (a son from an Aveirah of Kares, i.e. a Mamzer) a son for everything, even for Peru u'Rvu (does his father fulfill the Mitzvah through him) and [the decree] of Sheniyos? (Normally Mamzerim may marry each other. Do the decrees of Sheniyos apply to them?)

If a Nochri's son had Bi'ah with a Bas Yisrael and fathered a son, or a Ben Yisrael had Bi'ah with a Nochris [and she gave birth], and after [he or] she became a Yisraelis (converted, she became pregnant from him again and) she gave birth, [the son] is a Bechor for inheritance (he gets a double portion, for he is considered the father's first son), but he is not a Bechor for giving five Shekalim to a Kohen (he is not the first to leave her womb).

If a Nochri had Bi'ah with a Nochris and she gave birth - R. Yochanan says, there is lineage among Nochrim. (If he converted later, he fulfilled Peru u'Rvu through those children.) Reish Lakish says, there is no lineage among Nochrim. (We explained this like PNEI MOSHE.)

Question: "Ba'Es ha'Hi Shalach Merodach Bladan ben Bladan Melech Bavel Sefarim u'Minchah El Chizkiyah..." (shows that they have lineage)!

Answer: Since he showed honor to his grandfather (Merodach would sign 'ben Bladan'), he merited to be attributed to his ancestors.

Question: It says "va'Yishlach ha'Melech Asa El Ben Hadad ben Tavrimum ben Chaziyon Melech Aram ha'Yoshev b'Damesek Leimor"!

Question: [That was said for his disgrace - he was a] murderer the son of a murderer.

Support: This is like it says "Haman ben ha'Medasa" - was he ha'Medasa's son?! (Ha'Medasa was the son of Agag, more than 400 years earlier!)

Rather, he is a tormenter, the son of a tormenter. Also here, - he was a murderer the son of a murderer.

(R. Tanchuma): So Reish Lakish answered R. Yochanan - it says "ul'Tziva Chamishah Asar Banim v'Esrim Avadim." Do slaves have lineage?! (Surely they do not, and even so the verse calls his children Banim!)

Rebuttal: [The verse comes to] count what Mefivoshes lost (when David gave half of Mefivoshes' field to Tziva, he also freed Tziva).

Implied question: [What is the source that children from] a Shifchah [are not considered his children]?

Answer: It says "ha'Ishah v'Yeladeha Tihyeh l'Adoneha" [the wife and children remain with the master]. (The verse teaches that when an Eved Ivri is freed, the Shifchah with whom he had children remains with the master as do the children. This teaches that they are not considered children of the Eved Ivri.)

Implied question: [What is the source that children from] a Nochris [are not considered his children]?

Answer (R. Yochanan citing R. Shimon ben Yochai): It says "Lo Sischaten Bam", and it says "Ki Yasir Es Bincha me'Acharai" - your son from a Yisrael (i.e. from a Yisraelis) is called your son, but your son from a Nochris is not called your son, rather, her son (he is a Nochri. The verse discusses marrying your son to a Nochris, and your daughter to a Nochri. The Torah is concerned Ki Yasir, i.e. he (your Nochri 'son-in-law') veer your grandchild away from Hash-m, for your grandchild from him is a Yisrael. It is not concerned Ki Tasir (she, your Nochris 'daughter-in-law') veer your grandchild, for your grandchild from her is a Nochri.)

Yakov, the esteemed man of Kefar Nevuriyah, went to Tzur. They asked him 'may one circumcise on Shabbos the son of a Nochris [from a Yisrael]?

Suggestion: He wanted to permit, based on "va'Yisyaldu Al Mishpechosam l'Veis Avosam" (lineage follows the father. Since he is a Yisrael, the child is a full Yisrael. Therefore, there was no need to teach Ki Tasir, for we already know that a Yisrael's son, even from a Nochris, is a Yisrael.)

Rebuttal: R. Chagai heard, and said 'bring [Yakov] to lash him [for giving such a ruling].'

Question (Yakov): What is your source to [say that I erred, and] lash me?

Answer (R. Chagai): We learn from "v'Atah Nichros Bris lei'Lokeinu [to expel our Nochri wives and those born from them", for they are not Yisraelim].

Yakov: Do you lash me based on a verse from Kesuvim?! (We cannot learn Halachah from there. Perhaps Ezra enacted this for a Hora'as Sha'ah, or Hash-m told him to do so!)

R. Chagai: "Vecha'Torah Ya'aseh" (the Halachah follows this).

Question (Yakov): From which verse do we learn [that this is the Halachah]?

Answer (R. Chagai): It is from what R. Yochanan cited from R. Shimon ben Yochai): It says "Lo Sischaten Bam", and it says "Ki Yasir Es Bincha me'Acharai" - your son from a Yisrael (i.e. Yisraelis) is called your son, but your son from a Nochris is not called your son, rather, her son.

Yakov: Lash [me] your lashes - it is good for me to absorb (learn a lesson from this - YEFE MAR'EH).
