Deuteronomy 21:2

Deuteronomy 21 gives laws for an unsolved murder, in which the elders of the nearest city kill an unworked heifer in a rough valley and wash their hands to disclaim guilt before the Lord. It also covers marrying a captive woman, protecting the firstborn's double inheritance even if his mother is the less-loved wife, and the stoning of a stubborn, rebellious son. The chapter closes by commanding that a hanged man be buried the same day, since one hanged on a tree is accursed of God, so that the land is not defiled.
