Deuteronomy 14:21; Deuteronomy 21:23; Deuteronomy 28:26

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.

23 His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.

26 And thy carcase shall be meat unto all fowls of the air, and unto the beasts of the earth, and no man shall fray them away.
