I would like to ask a question regarding something I am quite confused by. Why is it okay to wear leather from an animal slaughtered not in a kosher fashion yet you cannot eat that animal's meat? To simplify this question and keep it in context, let's keep this as our primary example. I think a cow would be the perfect jumpoff point for this question. If I understand correctly, the primary reason Jewish people cannot eat just any beef/meat from a cow is that it must be slaughtered in a humane way, according to certain laws, in order to spare the animal undue pain and suffering. Assuming this is the primary reason for this specific example, why is wearing the skin of this animal (cow) which may or may not have been slaughtered in a kosher way okay?

  • "Assuming this is the primary reason" - you know what they say about when you assume... the fact is that only (human) FOOD must be slaughtered ritually. This doesn't apply to killing non-kosher animals or kisher ones killed for non-food purposes. Clearly, the requirement for "humaneness" is not the defining purpose of the commandment, else it would be forbidden to kill ANY animal without ritual slaughter, regardless of intended use. – Isaac Kotlicky Mar 17 '17 at 19:26

The short answer "Because G0d said so"

The longer explanation, fills up volumes of books explaining "why" Hashem said so. You can start with Maimonides "Moreh L'nivuchim' (Guide for the Perplexed), as well as all the books that comment on it. While one of the reasons for the laws may include the humane treatment, the laws of ritual slaughter are not just for humane reasons, or for health reasons, or for any other possible reason, but for raising the meat that we eat to the level of a sacrifice (again among others). The requirement to treat an animal humanely is a separate restriction and applies no matter if the animal is to be eaten or not. Thus the requirement not to cause "tza'ar baalei chaim" (pain to living creatures) would require one to kill an animal humanely, whether by kosher slaughter or some other means.

Note also that there are many means of slaughtering humanely (although shechitah seems to be the most humane) none of which will allow a Jew to eat the meat. Additionally, if a person treats an animal inhumanely, but does not cause it to develop signs of treifus (such as lung lesions), then the meat would still be kosher after shechitah. On the other hand, if he treats it completely humanely and just misses cutting both the windpipe and the esophagus (to the 51% mark) by just a fraction (such as 49.99999% rather than 50.0000001%) the animal is not kosher.

Given that the Torah does not forbid the use of an animal that has not been slaughtered by shechitah (it is mutar b'hana'ah) we see that if someone has violated the laws of "humane treatment", then he is the one who has done wrong. The sin does not attach to the object. Note that the Torah has to explicitly forbid the use of meat cooked in milk (for a non food purpose) (asur be-hana'ah) as well as forbidding the actual cooking itself.


Basically, the Bible says only eat it if it was killed properly. If it died any other way, you can feed it to your pet (i.e. you can derive benefit from it), just don't eat it. The same would apply to a cow that died of old age! There are only three categories of dead animals -- "kosher slaughtered"; "kosher slaughtered but it was going to die soon anyhow of disease or injury"; and "died some other way."

Presumably, eating something signifies a deeper connection.

  • How about Shor Haniskal, Chulin Baazara etc. which are Asur BaHanaah? – Double AA Apr 13 '14 at 2:37
