The Nitei Gavriel Pesach 2 Chapter 43:9 brings in the name of the Shevet Halevi that since a convert is as if he is newly born there is a question whether he is still considered a Bechor. Therefore the Nitei Gavriel concludes that it is best that he should either make a Siyum or be part of a Seudas Mitzva.

R Eliezer Dunner of Bene Brak told me, a ger firstborn, to fast. (The siyumim had already concluded.)

The Vilna Gaon (OC 470, s.v. v'ein) explains the opinion that exempts women from fasting as due to the fact that women lack k'dushas b'choros (the sanctified status of firstborns). A male with an older sister also lacks k'dushas b'chor since he is not a firstborn, so the opinion that exempts the older sister would certainly exempt the brother. In fact, a ...

Mishna Bekhorot 1:7 מצות פדייה קודמת למצות עריפה, שנאמר "אם לא תפדה וערפתו"‏ The Mitzva of redeeming precedes the Mitzva of [killing], as it says "And if you don't redeem is, [kill] it". So the owner could choose to kill it, but that's not what he's supposed to do. This is actually just like Yibbum, as the Mishna continues to explain, at least in ...

Due to Egyptian immorality, there were actually a lot of firstborns. All of these were counted: Firstborn of the mother Firstborn of the father Male Female Oldest in the house, even if not a firstborn All Egyptian firstborns, even in other countries Firstborns of other nationalities currently in Egypt Rashi to Ex. 12:30, s.v. כי אין בית אשר אין שם מת and ...

The Rambam (Hil. Bikkurim 12:1) writes: מצות עשה לפדות כל אדם מישראל פטר חמור בשה ואם לא רצה לפדותו מצות עשה לעורפו שנאמר ופטר חמור תפדה בשה ואם לא תפדה וערפתו ושתי מצות אלו נוהגות בכל מקום ובכל זמן ומצות פדייה קודמת למצות עריפה: It is a positive commandment for every Jewish man to redeem the first [male] issue of a donkey with a seh. If he ...

Because of the safek discussed by the Shevet HaLevi, Rav Elyashiv shlit"a recommends "that these bechorim participate in a seudas mitzvah." (http://torah.org/advanced/weekly-halacha/5758/pesach.html; Harav Y.S. Elyashiv - Seder ha-Aruch, vol. 3, pg. 44).

If a father says "my bechor will not take double" or says "he will inherit like a regular son" it is invalid. It violates the commandment of not diverting inheritance Devarim 21:16 If the son agrees to give up his portion some permit it. Nesivos 281:6 See pischei choshen hilchos yerushah 4:6-8 for a complete discussion . A firstborn's portion is ...

According to the always-reliable Wikipedia, this is a machlokes. R' Elyashiv recommends participating in a seudas mitzva, and thus, breaking the fast early, in order to avoid this problem. There is some discussion among the poskim (halakhic authorities) regarding whether a firstborn born through caesarean section is required to observe this fast, given ...

Rama in Orach Chaim 470:2 says that a father fasts for a son who is a Bechor

The "birthright" as used here that went to Yoseph is the "double portion". The Artscroll commentary on Reuven cites Targum Yonasan as pointing out that there were three items that had been originally given to the first born. Rashi says: you do not deserve to serve in the superior positions that were designated for you. Targum Yonatan says: But ...

The source for this is derasha in the Talmud (Ketubot 103a): כבד את אביך ואת אמך את אביך זו אשת אביך ואת אמך זו בעל אמך וי"ו יתירה לרבות את אחיך הגדול Honor your father [et avikha] and your mother [ve’et immekha]. The preposition et in the phrase: Your father; this teaches that you must honor your father’s wife. Similarly, the preposition et in the ...

The verses strongly indicate that not only did Avraham not give a double portion to Yishmael, he gave (basically) everything to Yitshak. For example, right before stating that Avraham died, Genesis (25:5) states that he gave all of his possessions to Yitshak: וַיִּתֵּ֧ן אַבְרָהָ֛ם אֶת־כָּל־אֲשֶׁר־ל֖וֹ לְיִצְחָֽק And Avraham gave all he had to ...

It depends what relevance of the term "BECHOR" you are asking about: If you mean BECHOR for Pidyon Haben, redemption of the firstborn son, the father does not have to redeem his son, even though the child is born from a forbidden union. (see Shulchan Aruch YD 305:19). Anyway there would be no pidyon haben because pidyon haben is only for the MOTHER'S ...

There is a big machlokes about whether a fast day can be on Friday (with the exception of the 4 Fasts for the Temple which are divrei kabalah and thus remained fixed). This machlokes is expressed most clearly in the context of Taanis Esther when Purim falls on Sunday. The Meiri writes that one side says the fast should be on Friday (based on a gemara in ...

Per the Sefer Keser Kehuna 10:4 a minor Levi may only wash together with the adult Levi the Kohain. This is based on the Mordechai in Megila Perek 3 #815.

The firstborn, if a son, fasts. If the firstborn is a girl, then the first son is not the first born for the sake of this fast. http://sephardicjudaism.blogspot.com/2007/03/passover-first-born-if-son-fasts-on.html

Here is a summary of an answer via wikipedia The firstborn of one's mother is referred to in the Bible (Exodus 13:2) as one who "opens the womb" of his mother. Therefore, the firstborn of the father exclusively, although considered as a firstborn regarding his father's inheritance, is not considered as a firstborn regarding the requirement to be redeemed, ...

The redemption of every first born child is mandatory as we see in the pesukim that I reference. Shmos Bo 13:13 And every firstborn donkey you shall redeem with a lamb, and if you do not redeem [it], you shall decapitate it, and every firstborn of man among your sons, you shall redeem. Additionally, Bamidbar Korach 18:15 Every first issue of the ...

A sick person might be exempt from the fast. R Mansour at dailyhalacha writes Firstborns who are ill or otherwise frail are not required to fast, even if they do not attend a “Se’udat Misva.” R Eliezer Melamed, author of Peninei Halacha writes This fast is less strict than other fasts. All of the other fasts were instituted by the Sages, but Ta’...

In Emunot V'Deiot 3:9 R. Saadia Gaon explains that prior to the priesthood of Aaron and his sons, there were always specific people appointed to perform sacrificial services: The third [problem is presented by] the fact that God commanded all men to offer up sacrifices and then forbade such activities to everyone except Aaron and his children. But this, ...

The simple explanation of the birth of Peretz and Zerach is that Peretz was born first. After Zerach stretched out his hand the midwife tied a red string on it figuring that he would be the first born. However he put his hand back in and Peretz emerged first. 38:30 וְאַחַר יָצָא אָחִיו אֲשֶׁר עַל יָדוֹ הַשָּׁנִי וַיִּקְרָא שְׁמוֹ זָרַח: Afterwards, his ...

The OP asks about attending the siyum and only eating later at a different place and time? The Minchas Yitzchak (vol.9:45) and Rav Elyashav (I heard this from Rav Smith) both say (as do others) that the simchah of the siyum is what releases the fast. Therefore, you may eat later and elsewhere. One idea for this is the Gemara (Shabbos 118) that says when ...

Whether to concider a stillborn as the firstborn or not would depend on the stage of developement of the fetus and other variables, See Shulchan Aruch, Yoreh De'ah 305:22 & 23, with various commentaries and their opinions. But if you are discussing an early term abortion, before the fetus has human form than all would agree that the next child would be ...

I recently heard that Rabbi Elyashiv Zatzal always made a Siyum on Erev Pesach. Once a fellow asked him that he was not a Bechor as his mother had prior miscarriages so why does he make a Siyum every year. He said he knows he is not a Bechor he does it since the Rav is supposed to make a Siyum. It is quite likely that often a Bechor makes the Siyum since he ...

The Ohr Chaim on Bamidbar 3:45 writes that the firstborn will serve in the Third Temple. שאמרו ז"ל עתידה עבודה שתחזור לבכורות R' Yonathan Eybeschutz writes in Ahavat Yonatan on the haftorah for Emor, that in the future, there will be atonement for the sin of the golden calf, and thus the firstborn will return to temple service. I've seen many who are ...

From Wikipedia: If a firstborn attending a siyum does not hear the completion of the tractate, or if he does not understand what he hears, or if he is in the shiva period of mourning and is thus forbidden from listening to the Torah material being taught, some authorities rule that subsequent eating would not qualify as a seudat mitzvah and he would ...
