Mishnah Kelim 16:6-7

Sugya Map: The Ontology of Kesei (Vessels)

• Issue: What defines a keli (vessel) susceptible to tuma vs. a pashut (flat/non-receptacle) object?
• Nafka Mina: The kassiah (glove/covering). If it exists to "receive" (protect the user by catching debris), it is a keli (tamei). If it exists solely to absorb perspiration or provide comfort, it is a pashut (tahor).
• Primary Sources: Mishnah Kelim 16:6-7; Rambam, Hilkhot Kelim 7:5; Tosafot Yom Tov, Kelim 16:6.

Text Snapshot

The Mishnah Mishnah Kelim 16:6 posits: "This is the general rule: that which is made for holding anything is susceptible to uncleanness, but that which only affords protection against perspiration is clean."

• Leshon Nuance: The term kassiah (קסייה) is debated. Does it denote a glove (Rambam) or a headband/visor (Mahar'am)? The definition dictates the tuma status.

Readings

• Rambam: Argues that if the intent of the kassiah is to protect the hand from thorns or debris (catching/receiving), it is a keli. If it is designed to manage sweat, it is an accessory—a mere "flat" object—lacking the beit kibul (receptacle) requirement.
• Tosafot Yom Tov: Cites the Ra'avad, noting that the kassiah acts as a receptacle for the waste (chaff/dust). It is not merely "protection"; it is a functional tool that catches the refuse of the labor, thereby attaining the status of a keli.

Friction

• Kushya: If the kassiah of a dyer or blacksmith is tahor because it manages sweat, why isn't the winnower’s kassiah also tahor? Both are dealing with physical labor in extreme conditions.
• Terutz: The distinction lies in the kavannah (intent). The winnower’s glove is inherently a tool for the harvest—it catches the chaff. The dyer’s glove is an extension of the skin, designed solely for thermal regulation/hygiene, not to facilitate the "holding" of the product.

Intertext

• Compare with Shulchan Arukh, Orach Chaim 301, which discusses the laws of carrying on Shabbat. The categorization of an object as a keli or tashmish (accessory) often pivots on this exact threshold: does it serve the user or the object?

Psak/Practice

The heuristic is clear: Functional Intent Trumps Materiality. If an object’s primary purpose is to be an interface for holding/receiving (utility), it is a vessel. If it is a secondary buffer (comfort/hygiene), it remains pashut.

Takeaway

Halachic status often hinges on the distinction between utility and comfort. If you make it to hold the world, you’re a vessel; if you make it to manage yourself, you’re just a garment.
