Deuteronomy 22 - 25
Various rules pertaining to civil discourse and commerce between Israelites. Mercy and grace demanded upon those who cannot help themselves.
Chapter 25 details the law of the levirate marriage, which is designed to provide a legacy for a man who dies childless, as it was God’s command that the land each family inherited would remain in that same family going forward. The story of Ruth and Boaz provides an example of this, where Boaz married Ruth in order to raise up children in the name of Elimelech, and is a picture of Christ and His gentile bride.
