רש"י, ויקרא יז:ג
Who slaughters an ox, a lamb, [or a goat]: Scripture is speaking of [slaughtering] holy sacrifices [not of slaughtering ordinary animals], for Scripture continues, “to offer up as a sacrifice” (next verse). - [Torath Kohanim 17:91] [translation by Judaica Press]
Suggested Discussion Questions:
What is the difference between offering an animal for a sacrifice and the ordinary process of killing animals for food?
