A Kinsman Redeemer is a relative who has the responsibility to help family members in need, particularly in ancient Israelite culture. This role is outlined in the Hebrew Bible, specifically in the book of Ruth. The Kinsman Redeemer could redeem family property that had been sold, ensuring it remained within the family lineage. Additionally, the Kinsman Redeemer could marry a widow to preserve the family line, as seen in the story of Boaz and Ruth. This practice was important for maintaining family heritage and providing support during difficult times, reflecting the values of community and responsibility in ancient society.
