Deuteronomy 21:22–23

22 And if a man have committed a sin worthy of death, and he be to be put to death, and thou hang him on a tree: 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 accursedc of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
