Deuteronomy 21:23

his body shall not remain all night upon the tree, but thou shalt in any wise bury him that day, before sunset, (for he that is hanged is accursed of God,) rejected as detestable and as defiling the land, that thy land be not defiled, morally, by the presence of this curse above the ground, which the offender had no longer been worthy to tread, which the Lord, thy God, giveth thee for an inheritance. This rule was carried out also in the case of Jesus, John 19:31, because, as St. Paul writes, He became a curse for our sakes, Galatians 3:13.
