Leviticus 7:24
And the fat of the beast that dieth of itself, and the fat of that which is torn with beasts, may be used in any other use: but ye shall in no wise eat of it.
And the fat of the beast that dieth of itself,.... Of any disease, and is not regularly killed:
And the fat of that which is torn with beasts; with wild beasts:
may be used in any other use; as in medicine, for plasters, or for making candles, or for greasing of anything to make it smooth and pliable, or the like:
but ye shall in no wise eat of it; such carcasses themselves were not to be eaten of, and one would think their fat in course must be unlawful; but however, to prevent the doing of it, this particular law was given, and those that broke this were doubly guilty, as the Jews observe {m}; once in eating things that died of themselves, or were torn with beasts, and again by eating the fat of them.
