Deuteronomy 14:21

You are not to eat any carcass; you may give it to the foreigner residing within your gates, and he may eat it, or you may sell it to a foreigner. For you are a holy people belonging to the Lord your God. You must not cook a young goat in its mother’s milk.
BSB · Berean Standard Bible
Ye shall not eat of any thing that dieth of itself: thou shalt give it unto the stranger that is in thy gates, that he may eat it; or thou mayest sell it unto an alien: for thou art an holy people unto the Lord thy God. Thou shalt not seethe a kid in his mother’s milk.
KJV · King James Version
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 the Lord your God. You shall not boil a young goat in its mother’s milk.

Ye shall not eat of anything that dieth of itself: thou mayest give it unto the sojourner that is within thy gates, that he may eat it; or thou mayest sell it unto a foreigner: for thou art a holy people unto Jehovah thy God. Thou shalt not boil a kid in its mother’s milk.
