Ruth

Ruth provides the crucial link between the Judges era and David's monarchy, explaining David's great-grandmother. It demonstrates God's grace to Gentiles and shows faithful living during the chaotic Judges period.

A kinsman-redeemer (goel) was a close male relative who could redeem family property, avenge blood, and marry a widow to continue the family line. Boaz fulfilled this role for Ruth, becoming a picture of Christ's redemption.

Ruth's inclusion demonstrates that God's plan always included all nations, not just Israel. Her genealogy itself proclaims grace to outsiders.

Ruth 1:1 places the story 'in the days when the judges ruled,' probably around 1150-1100 BC. Since David was Obed's grandson, this timing fits the historical framework.
