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 ...

Some thoughts: Rashi in Shemot 1:7 tells us that the Jewish Women gave birth to children 6 at a time. If Moshe's family is any indication there were 4 generations of Jews born during the Jews stay in Egypt. Either way, only the children of the last generation (for the most part) would have been younger than 60 and therefore counted in the census. Even ...

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 ...

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 ...

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).

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 ...

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 ...

Some portion of the 600k males were not married, and some of the married ones had no children at all. Of those that were, only 22k families had first-borns which needed to be redeemed by a Levite or 5 shekalim. Not all firstborns need redemption, in fact, a Pidyon heBen ceremony is relatively rare. As you already noted, the child must be male. If the ...

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.

Indeed the laws of firstborn animals (bechor) apply today and the Shulchan Aruch (YD 320:6) rules that we should avoid creating bechorot because the laws are very complex and people will likely make mistakes, AND because we can't bring them as korbanot nowadays anyway. He suggests that you sell to a gentile a part of the pregnant mother to make you a partner ...

In grade school (or so), I learned (though I don't remember from whom/where) that things that were obvious to those with a stronger m'sora were not written down; later generations' respective rabbis wrote them as those rabbis realized that the matters were not so obvious to their own contemporaries. This is a sort of extension of the es laasos lAshem that ...

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, ...

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 ...
