NET

21 You may not eat any corpse, though you may give it to the resident foreigner who is living in your villages and he may eat it, or you may sell it to a foreigner. You are a people holy to the Lord your God. Do not boil a young goat in its mother’s milk.

Darby

21 Ye shall eat of no carcase; thou shalt give it unto the stranger that is within thy gates, that he may eat it, or sell it unto a foreigner; for thou art a holy people to Jehovah thy God. Thou shalt not boil a kid in its mother's milk.

KJV

21 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.
