Plucking Wool Without Violating the Shearing Prohibition

How the Sages distinguish plucking from shearing to permit preparing a blemished firstborn for slaughter.

כׇּֽל־הַבְּכ֡וֹר אֲשֶׁר֩ יִוָּלֵ֨ד בִּבְקָרְךָ֤ וּבְצֹֽאנְךָ֙ הַזָּכָ֔ר תַּקְדִּ֖ישׁ לַיהֹוָ֣ה אֱלֹהֶ֑יךָ לֹ֤א תַעֲבֹד֙ בִּבְכֹ֣ר שׁוֹרֶ֔ךָ וְלֹ֥א תָגֹ֖ז בְּכ֥וֹר צֹאנֶֽךָ׃

YoubYou See note at 12.5. shall consecrate to the ETERNAL your God all male firstlings that are born in your herd and in your flock: you must not work your firstling ox or shear your firstling sheep. (Deuteronomy 15:19)

Consecration and the Ban on Shearing

In the book of Devarim, after detailing laws of charity, debt cancellation, and the Hebrew bondsman, the Torah commands the consecration of firstborn animals. Sforno explains that offering the firstborn male flock and herd expresses gratitude to God as the source of all wealth. Ibn Ezra notes that this follows the laws of servitude because both passages restrict human labor.

The verse concludes with a dual prohibition against exploiting a sanctified animal: one must not work a firstborn ox or shear a firstborn sheep. Rashbam explains that the command to consecrate the animal means treating it with sacred dignity by refraining from labor and shearing.

לֹ֤א תַעֲבֹד֙ בִּבְכֹ֣ר שׁוֹרֶ֔ךָ וְלֹ֥א תָגֹ֖ז בְּכ֥וֹר צֹאנֶֽךָ׃

You must not work your firstling ox or shear your firstling sheep. (Deuteronomy 15:19)

Preparing the Blemished Firstborn

A בכור (firstborn male animal) that incurs a permanent blemish loses its altar status and may be slaughtered and eaten. However, sheep often develop overgrown wool while the owner waits for a blemish to appear. When preparing to slaughter, dense wool at the throat can obstruct the incision,.

Similarly, wool may obscure an injury and prevent an expert Sage from inspecting a suspected permanent blemish,. The owner faces a dilemma: he needs to clear the wool, but the Torah expressly forbids shearing a firstborn animal,.

Shearing Versus Plucking Wool

To resolve this dilemma, the Mishnah analyzes the precise language of the verse. The Torah commands "you shall not shear," using the verb for גזיזה (shearing with a blade). The biblical commandment forbids severance of the fleece by cutting, but does not prohibit תלישה (plucking hair out).

Rabbi Yosei ben HaMeshullam rules that one may clear a path by uprooting the fleece by hand or with a cleaver before slaughter. Rashi confirms that plucking is fundamentally distinct from shearing, meaning biblical shearing is not violated through this method.

ותולש את השער - לכאן ולכאן למקום חתך הסכין משום חלדה ולא אמרינן גוזז הוא את הבכור

And plucks the hair — to here and to there, at the site of the knife's incision... and we do not say that he is shearing the firstborn. (Rashi on Bekhorot 24b:5:2)

Keeping Plucked Wool in Place

Although Torah law permits plucking, the Sages instituted a protective safeguard. If an owner removed the plucked wool and kept it, onlookers would suspect that he sheared consecrated fleece for personal benefit.

Therefore, Rabbi Yosei ben HaMeshullam insists on a crucial caveat: the slaughterer may pluck the wool only on condition that he does not move it from its place. The fleece must remain entangled with surrounding wool so that it never appears as commercial shearing.

עוֹשֶׂה מָקוֹם בְּקוֹפִיץ מִיכָּן וּמִיכָּן, וְתוֹלֵשׁ אֶת הַשֵּׂעָר, וּבִלְבַד שֶׁלֹּא יְזִיזֶנּוּ מִמְּקוֹמוֹ

He clears space with a cleaver from here and from there, and plucks the hair, provided that he does not move it from its place. (Bekhorot 24b:5)

Clearing Wool Without Transgression

The Gemara confirms that Rav ruled the halacha follows Rabbi Yosei ben HaMeshullam throughout his teachings,. Whenever one needs to clear space to slaughter a blemished בכור or inspect its blemish, one may pluck the fleece.

However, one must leave the plucked fibers intertwined on the animal's body,. By distinguishing precise biblical shearing from plucking while safeguarding against public misperception, the law balances facilitating proper ritual slaughter with preserving the sanctity of the firstborn,,.

Plucking wool from a firstborn sheep avoids the biblical prohibition against shearing, but the fleece must stay in place to avoid the appearance of illicit shearing.
