Overview
Chullin 139 continues the opening sugya of Shiluach HaKen and asks a fundamental question:
Why is a bird that belongs to Hekdesh exempt from Shiluach HaKen?
The daf then develops broad principles about ownership, Hekdesh, responsibility for consecrated property, and finally returns to the details of where Shiluach HaKen applies. The daf also contains the famous aggadic section asking, โWhere are Moshe, Haman, Esther, and Mordechai hinted to in the Torah?โ
Why Are Hekdesh Birds Exempt?
The Mishnah taught:
Shiluach HaKen applies to ordinary birds but not to birds of Hekdesh.
The Gemara asks how such a case could occur.
Various possibilities are considered:
- Consecrating a nest.
- Consecrating eggs.
- Consecrating chicks.
- Consecrating the mother bird.
After rejecting several cases, the Gemara explains the dispute between Rav and Shmuel.
Rav: Consecrated Doves That Flew Away
Rav explains the case as:
Someone consecrated birds from his dovecote and they later flew away.
Since they retain sanctity, they remain exempt from Shiluach HaKen.
Shmuel: A Consecrated Hen
Shmuel understands the case differently:
A person consecrated a hen to Bedek HaBayit.
Even if the bird later leaves his possession, Shmuel holds:
โืืโ ืืืจืฅ ืืืืืืโ
The bird remains within Hashemโs domain.
Therefore Shiluach HaKen does not apply.
Rabbi Yochanan and Reish Lakish
The Gemara then records a famous dispute.
Rabbi Yochanan
A consecrated bird that escapes:
Remains Hekdesh.
Reish Lakish
Initially argues:
Once it escapes, its sanctity should disappear.
The Gemara eventually explains and reconciles their positions through a broader discussion about responsibility for consecrated property.
Neder vs. Nedavah
The Gemara compares:
Neder
โI accept responsibility for an offering.โ
ืืจื ืขืื
Nedavah
โThis particular animal is an offering.โ
ืืจื ืื
The difference:
- Neder creates ongoing responsibility.
- Nedavah generally does not if the designated item is lost.
This becomes important when discussing Hekdesh that disappears.
The Rule of Rav Hamnuna
Rav Hamnuna teaches:
Regarding Arachin (valuations),
even when a person does not explicitly assume responsibility,
he still remains liable until payment reaches the Temple treasury.
The Gemara derives this from:
โืื ืชื ืืช ืืขืจืืโ
The money remains ordinary property until delivered to the treasurer.
Returning to Shiluach HaKen
The Gemara now explains the words:
โืื ืืงืจื ืงื ืฆืคืืจ ืืคื ืืโ
โWhen a birdโs nest happens before you.โ
You Donโt Have to Search
The Beraita teaches:
One might think a person must wander through mountains and forests looking for nests.
The Torah says:
ืื ืืงืจื
Only when one happens upon a nest.
The mitzvah is opportunistic, not something that must be pursued.
Where Does the Mitzvah Apply?
The Torah says:
ืืืจื
The Gemara expands this to include:
- Roads
- Fields
- Trees
- Pits
- Caves
Essentially anywhere one encounters a qualifying nest.
The Principle: Not a Nest You Own
The Gemara derives:
Just as a road is not under your ownership, so too the nest must not be fully under your control.
This explains the Mishnahโs exemption for:
- Domestic birds nesting in oneโs house.
- Fully controlled nests.
Famous Questions: Biblical Hints
A memorable aggadic passage follows.
The Gemara asks:
Moshe in the Torah?
โืืฉืื ืืื ืืฉืจโ
Haman in the Torah?
โืืื ืืขืฅโ
Esther in the Torah?
โืืื ืื ืืกืชืจ ืืกืชืืจโ
Mordechai in the Torah?
โืืจ ืืจืืจโ
translated as ืืืจื ืืืื
This is one of the most famous sections in the entire masechta.
A Nest in the Sea?
Rav Yehudah in the name of Rav teaches:
If one finds a nest in the sea, Shiluach HaKen applies.
Proof:
โืื ืืชื ืืื ืืจืโ
The word ืืจื can include the sea.
A Nest on a Personโs Head?
The Gemara humorously asks:
What if one finds a nest on top of a personโs head?
This triggers the famous โMoshe ืื ืืชืืจื ืื ืื?โ discussion.
The Gemara explores the verse:
โืืืืื ืขื ืจืืฉืโ
but leaves the discussion mostly as a vehicle for the aggadic teachings.
Domestic Pigeons
The Mishnah mentioned:
ืืื ื ืืจืืกืืืืช
The Gemara discusses whether the correct reading is:
- ืืจืืกืืืืช
- ืืืจืกืืืืช
One explanation relates the name to Herod.
Another traces it to a specific location.
A Story of Trained Birds
Rav Kahana describes observing a flock of pigeons communicating with one another.
One bird failed to respond correctly, and the flock interpreted it as blindness.
The story illustrates the remarkable behavioral patterns of domesticated birds and helps explain why such birds are considered โpreparedโ and exempt from Shiluach HaKen.
Why Only Kosher Birds?
The Gemara derives from:
ืงื ืฆืคืืจ
that Shiluach HaKen applies only to kosher birds.
The Gemara spends the final portion of the daf proving that the term ืฆืคืืจ in this context refers specifically to kosher species.
This discussion continues onto the next daf.
Big Idea of the Daf
The central theme of Chullin 139 is:
Shiluach HaKen applies only to a nest that โcomes your wayโ and is not already under your ownership or a competing sanctity.
At the same time, the daf broadens into a profound discussion of ownership, Hekdesh, and Hashemโs hidden presence in history, culminating in the famous allusions to Moshe, Esther, Haman, and Mordechai.
Final Summary
Chullin 139 explores why consecrated birds are exempt from Shiluach HaKen and develops major debates between Rav, Shmuel, Rabbi Yochanan, and Reish Lakish about Hekdesh and responsibility. The Gemara then defines the scope of Shiluach HaKen, teaching that it applies only when a nest is encountered naturally and is not already under oneโs control. The daf concludes with the celebrated aggadic section identifying hints to Moshe, Haman, Esther, and Mordechai in the Torah and begins proving that the mitzvah applies specifically to kosher birds.
