Overview

Chullin 117 concludes the eighth perek by comparing the halachic status of cheilev and dam in sacrificial animals. Although both are severe prohibitions, the Gemara demonstrates that the Torah assigned them very different legal consequences. The daf then opens a new perek dealing with the laws of tumah, specifically which animal components combine together to create food impurity and neveilah impurity.

 

Cheilev Is Subject to Meโ€™ilah

The Mishnah teaches that sacrificial fats (cheilev) are subject to:

  • Meโ€™ilah
  • Piggul
  • Notar
  • Tumah

The Gemara asks for the source and derives it from the comparison between the fats removed from a Korban Shelamim and those of the Par Kohen Mashiach.

Rabbi Chanina challenges the derivation, suggesting that it should instead come from the verse:

ื›ืœ ื—ืœื‘ ืœื”โ€˜

which includes the sacrificial fats in the laws of meโ€™ilah.

The Gemara ultimately explains why both derivations are necessary.

 

The Special Status of the Tail (Alyah)

The Gemara discusses whether the sheepโ€™s fatty tail (alyah) is included under the general term cheilev.

This issue is important because if it were fully treated as ordinary cheilev, it might become prohibited for consumption.

The Gemara concludes that while the Torah sometimes classifies the tail together with sacrificial fats, it is not automatically included under the ordinary prohibition of cheilev.

 

Why Blood Is Different

The Mishnah stated:

What applies to cheilev does not apply to blood.

The Gemara asks for the source.

Several answers are given:

  • From the word โ€œืœื›ืโ€ โ€” blood was given to Israel for atonement.
  • From โ€œืœื›ืคืจโ€ โ€” it was designated for atonement, not meโ€™ilah.
  • Rabbi Yochanan derives from โ€œื”ื•ืโ€ that blood has the same status before and after atonement.

The result:

Blood is excluded from the laws of meโ€™ilah.

 

Once a Mitzvah Is Completed

The Gemara asks why blood should lose meโ€™ilah after it has fulfilled its purpose.

This leads to a broader principle:

Generally, once an itemโ€™s mitzvah has been performed, meโ€™ilah no longer applies.

The Gemara compares this to:

  • Terumat HaDeshen
  • Bigdei Kehunah
  • Eglah Arufah

and analyzes why those cases do not prove otherwise.

 

Beginning of Perek HaOr VeHaRotav

The new Mishnah opens:

ื”ืขื•ืจ ื•ื”ืจื•ื˜ื‘ ื•ื”ืงื™ืคื” ื•ื”ืืœืœโ€ฆ

The subject now changes completely.

The Mishnah discusses:

  • Hide
  • Broth
  • Residual tissue
  • Bones
  • Sinews
  • Horns
  • Hooves

and asks whether they combine with meat for purposes of Tumat Ochlin and Tumat Neveilah.

 

Tumat Ochlin vs. Tumat Neveilah

The Mishnah establishes an important distinction:

These attached substances may combine to create:

โœ… Tumat Ochlin

but generally not:

โŒ Tumat Neveilah

The Gemara immediately connects this to the concept of shomrim (protective coverings).

Shomer for Light Tumah but Not for Neveilah

The Gemara brings the teaching:

ืฉื•ืžืจื™ื ืœื˜ื•ืžืื” ืงืœื” ื•ืœื ืœื˜ื•ืžืื” ื—ืžื•ืจื”

Protective coverings count for ordinary food impurity but not for the more stringent tumah of neveilah.

The proof comes from:

  • โ€œืขืœ ื›ืœ ื–ืจืข ื–ืจื•ืขโ€ regarding food impurity.
  • โ€œื‘ื ื‘ืœืชื”โ€ excluding certain attached materials from tumat neveilah.

 

Big Idea of the Daf

The daf serves as a transition:

The end of Kol HaBasar clarifies why sacrificial cheilev and dam are treated differently regarding meโ€™ilah and other sacrificial laws.

The beginning of HaOr VeHaRotav shifts to an entirely new subject: determining what parts of an animal are considered significant enough to create or combine for tumah.

This is the true structure of Chullin 117.
