Leviticus 11:39

And if any beast of which ye may eat die
Any clean beast, as the ox, sheep, goat, deer what, if rightly killed, is very lawful to eat of; but if it died of itself through any distemper, or was torn by the wild beasts, so the Targum of Jonathan:

he that toucheth the carcass thereof shall be unclean until the
even;
not the bones, nerves, horns, hoofs, or skin, as Jarchi observes; these might be handled, because some of them, at least, were wrought up into one instrument or another, by artificers, for use and service, but the flesh of them might not be touched; whoever did touch it was ceremonially unclean, and might not go into the sanctuary, or have conversation with men, until the evening of the day in which this was done.
