Bekhorot 19 – בכורות י״ט | Daf Yomi with Rashi, Tosafot, the Rambam and halacha
What Bekhorot 19 teaches
- Rabbi Akiva rules that neither a caesarean offspring nor its subsequent sibling is sanctified, because a firstborn must satisfy both conditions.
- Rabbi Akiva holds that uterine discharge or afterbirth exempts subsequent births from bechor status, even before an animal delivers a live offspring.
- The Rabbis rely even on statistical majorities, permitting minor orphans to enter levirate marriage without fearing they are sterile.
The sugyot
- The Gemara concludes that each case was necessary, establishing that an offspring born to a first-time mother is inherently superior.
- Rabbi Tarfon and Rabbi Akiva dispute whether an animal born by caesarean section or its subsequent womb-born sibling possesses the sanctity of a firstborn.
- The Gemara establishes that an animal firstborn in only one aspect is not sanctified, reconciling the biblical verses according to Abaye.
- The Mishnah debates whether age guarantees firstborn status for an animal bought from a gentile, given that uterine discharges also exempt.
- The Gemara asks why a goat bought after its first year is a doubtful firstborn given the majority, attempting and rejecting a distinction in majorities.
