Deuteronomy 21:22-23

22“And if a man has committed a sin worthy of death, and he is put to death and [afterward] you hang him on a tree [as a public example],

23his body shall not hang all night on the tree, but you shall most certainly bury him on the same day (for he who is hanged is cursed by God), so that you do not defile your land which the Lord your God gives you as an inheritance.
