Deuteronomy 14:20

18And the stork, and the heron after her kind, and the lapwing, and the bat.

19And every creeping thing that flieth is unclean unto you: they shall not be eaten.

20But of all clean fowls ye may eat.

21Ye shall not eat of anything 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.

22Thou shalt truly tithe all the increase of thy seed, that the field bringeth forth year by year.
