Deuteronomy 14:21

14:21 You shall not eat of anything that dies of itself: you may give it to the foreigner living among you who is within your gates, that he may eat it; or you may sell it to a foreigner: for you are a holy people to Yahweh your God. You shall not boil a kid in its mother's milk.
