The masechet so far, chapter by chapter

Masechet Bekhorot details the laws of sanctified firstborn animals, human firstborn status, priestly physical blemishes, and redemption obligations. Through Daf 48, the tractate shifts from the sacrificial rules and bodily flaws of animals and priests to the financial laws of human firstborn inheritance and redemption.

Chapter 1 – הלוקח עובר חמורו: Firstborn Donkeys and Their Redemption

This chapter addresses the obligation to redeem a firstborn male donkey with a sheep or goat. Gentile ownership or partnership in the mother or fetus completely exempts the donkey from firstborn status. If the owner refuses to redeem the donkey, its neck must be broken.

Gentile partnership in a pregnant donkey exempts the offspring from firstborn sanctity.
A firstborn donkey is redeemed with a sheep or goat, or else its neck is broken.
The owner bears no liability if a designated redemption lamb dies before reaching the priest.

Chapter 2 – הלוקח עובר פרתו: Kosher Animal Firstborns and Uncertain Births

This chapter examines the sanctity of firstborn kosher livestock, such as cattle and sheep, which must be given to a priest for sacrifice. It details how pre-existing blemishes affect consecration and discusses cases where animal ownership is shared with gentiles. The mishnayot also resolve uncertainties surrounding multiple births and caesarean deliveries.

Animals dedicated with permanent blemishes hold only monetary sanctity, so redemption permits shearing and milk use.
A gentile's right of seizure on guaranteed livestock exempts the offspring from firstborn sanctity.
For twin male births, Rabbi Tarfon awards the priest the fatter lamb, while Rabbi Akiva gives the leaner.

Chapter 3 – הלוקח בהמה: Signs of Prior Birth and Wool Restrictions

This chapter explores how to determine whether an animal purchased from a gentile has previously given birth. Physical signs such as murky uterine fluid or an expelled afterbirth establish a prior birth and exempt subsequent offspring. The chapter also establishes rules regarding shearing and handling loose wool from a firstborn.

A murky uterine discharge or expelled afterbirth proves prior pregnancy, exempting future offspring from firstborn status.
A purchased nursing animal is presumed to have calved, exempting her subsequent offspring from firstborn sanctity.
Plucking wool on a firstborn to inspect a blemish or facilitate proper slaughter is permitted ab initio.

Chapter 4 – עד כמה: Rearing Periods, Inspectors, and Witness Credibility

This chapter specifies the mandatory duration an owner must tend to a firstborn before delivering it to a priest. It regulates the examination of blemishes by recognized court experts and sets guidelines for inspection fees. It also outlines legal distrust, defining when individuals suspected of transgressions are disqualified from testifying or adjudicating.

Owners must care for a firstborn sheep thirty days and cattle fifty days before priestly delivery.
Authorized court experts like Rabbi Tarfon are entirely exempt from paying restitution for mistaken rulings.
Inspectors may take fixed wages for lost time, but judges who take fees have their rulings voided.

Chapter 5 – כל פסולי המוקדשין: Selling Disqualified Offerings and Causing Blemishes

This chapter contrasts the public market sale of Temple sacrifices with the private, home sale of blemished firstborns and animal tithes. It severely penalizes anyone who intentionally inflicts a blemish on a firstborn to permit its slaughter. The chapter also clarifies when owners and shepherds are deemed credible to testify about injuries.

Disqualified offerings sell in public markets, while blemished firstborns may be sold and weighed only at home.
Intentionally blemishing a firstborn permanently forbids slaughtering it until an unrelated, natural blemish develops.
Three laymen may permit slaughter of an obviously maimed firstborn if no local expert exists.

Chapter 6 – על אלו מומין: Disqualifying Physical Blemishes on Livestock

This chapter catalogs permanent physical blemishes that disqualify a firstborn animal from the altar and permit its slaughter outside the Temple. Covered defects include splits in ear cartilage, eye cataracts, facial deformities, and limb anomalies. Transient flaws, skin abrasions, and hidden internal conditions do not permit outside slaughter.

Ear blemishes require exposed cartilage splits, notches catching a fingernail, or holes passing a bitter vetch legume.
A tevallul blemish occurs only when white tissue extends into the black pupil of the eye.
Boils moist inside and out are temporary flaws, whereas permanent dry boils permit slaughter outside the Temple.

Chapter 7 – מומין אלו: Disqualifying Blemishes in Temple Priests

This chapter details physical blemishes and bodily anomalies that disqualify a priest from performing the sacrificial service in the Temple. Many animal blemishes also disqualify priests, alongside human-specific flaws like abnormal cranial shapes, eye defects, and asymmetrical limbs. Transgressions involving forbidden marriages or corpse contamination also bar a priest from service until rectified.

Abnormal head shapes, missing eyebrows, or sunken noses disqualify priests from performing the Temple service.
Amputating an extra digit containing bone leaves a priest disqualified as someone permanently missing a limb.
A priest in an illicit marriage cannot serve in the Temple until taking a vow of separation.

Chapter 8 – יש בכור: Human Firstborn Inheritance and Redemption

This chapter distinguishes between a firstborn son with respect to a double inheritance portion and a firstborn requiring five sela coins for redemption from a priest. Miscarriages, maternal status, and prior births determine which status applies to a subsequent child. It also navigates unresolved paternity and intermingled infants among multiple wives.

Caesarean-born sons and their subsequent brothers are exempt from both double inheritance and the five-sela redemption.
A father pays five sela for doubtful twin boys, but pays nothing if one dies within thirty days.
If intermingled boys die after thirty days, divided brothers are treated as purchasers against oral debts.
