Exodus

Then said I, Ah Lord God! behold, my soul hath not been polluted: for from my youth up even till now have I not eaten of that which dieth of itself, or is torn in pieces; neither came there abominable flesh into my mouth.

Speak unto all the congregation of the children of Israel, and say unto them, Ye shall be holy: for I the Lord your God am holy.

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 every soul that eateth that which died of itself, or that which was torn with beasts, whether it be one of your own country, or a stranger, he shall both wash his clothes, and bathe himself in water, and be unclean until the even: then shall he be clean.

That which dieth of itself, or is torn with beasts, he shall not eat to defile himself therewith: I am the Lord.
