Daf 16 — Chullin 16 Summary

Chullin 16 – Good Morning Raboisai Shechita with a Machine ( מוקני ) Gemara: • One who shechts using a מוקני (machine / wheel system) Case: • Knife attached to a rotating wheel • Person activates it Result: • שחיטה כשרה כוח אדם vs כוח אחר Gemara distinguishes: • כוח אדם (human force) Valid • כוח אחר (external force) Invalid Case – Water Wheel • If water turns the wheel Why it should be כשר : Person opened the water Initial movement comes from him Limitation: Only the initial force ( כח ראשון ) After that: • Movement is from water Not considered his כוח Proof – Water Damage Case Case: • Person directs water onto someone • Person dies If from initial force: • חייב If later force: • פטור Same distinction: • כוח ראשון vs כוח שני Knife – תלוש vs מחובר Gemara discusses: • Must shechita be with something detached ( תלוש ) ? Source Discussion: • Avraham Avinu took a knife Question: • Does this prove requirement of תלוש ? Conclusion: Not a proof Pasuk only describing what happened תלוש ולבסוף חיברו Case: • Object was detached • Then attached Question: • Is it considered תלוש or מחובר ? Comparison – עבודה זרה • Mountain ( מחובר ) Cannot become אסור • House (was תלוש → now מחובר ) Can become אסור Shows: • תלוש remains significant Tumah – Water Usage Case: • Water must be desired for use Distinction: • Water used for כלי Valid • Water used for wall ( מחובר ) Not valid סוגי קירות Gemara distinguishes: • Natural wall (from creation) Fully מחובר • Built wall Different status Knife in Wall Case: • Knife inserted into wall Question: • Is it considered מחובר ? Answer: • Knife is not fully מבוטל to wall Therefore: • Retains status of תלוש Proof Case – Stone / Reed • If fully part of ground Problematic Because: • Always מחובר Final חילוק Difference: • Always מחובר Invalid • תלוש then attached Better status Position of Knife Case: • Knife fixed in wall Two possibilities: • Animal moved against knife • Knife moved against animal Result: • Certain positions valid • Certain positions problematic Sharp Materials Mishna: • Can shecht with: o Knife o Reed o Stone Not allowed: • Serrated tools • Nail / teeth Reason: • Causes tearing Splintered Reed Case: • Reed with splinters Not allowed Reason: • Tears instead of smooth cut Additional Uses (Reed) Gemara: • Not used for: o Milah o Cutting meat o Toothpick Concern: • Splinters Exception • Smooth reed Allowed Birds vs Animals Mishna: • שחיטה applies to: o Animals o Birds Meat Consumption Gemara: • Originally: Meat restricted • Later: Allowed Key Takeaways (English) • Machine shechita valid if powered by human force • Distinction: כוח ראשון vs כוח שני • תלוש vs מחובר is central • תלוש ולבסוף חיברו retains significance • Knife in wall may still be considered detached • Fully attached objects are problematic • Shechita requires smooth cutting • Splintered materials invalid • Position of knife affects validity • Meat became permitted outside Mikdash context Catch up, review, download previous Dafim & more: https://www.dafchazarah.co.uk Now available as an app (Apple, Google & Amazon): https://dafchazarah.co.uk/download Sponsor a day: https://dafchazarah.co.uk/sponsor To receive the daf summary daily join our group: https://chat.whatsapp.com/L4AiVVxQwYqLRh4RtMAlGE לעילוי נשמת אמי מורתי רות בת הרב מנחם מנדל
