Boaz's words to Ruth reflect the ancient Israelite practice of the kinsman-redeemer, a role that involved protecting and supporting family members in distress. This practice was part of the Levirate law, where a close relative had the responsibility to marry a widow to preserve the family lineage and property. Boaz assures Ruth that he will fulfill this duty if the nearer kinsman does not. His promise is both a legal and a personal commitment, demonstrating his integrity and compassion.
This moment is significant as it underscores the themes of loyalty, protection, and divine providence that run throughout the Book of Ruth. Boaz's actions are not just about following legal obligations but also about showing kindness and ensuring Ruth's well-being. His statement, "as surely as the Lord lives," underscores his sincerity and the seriousness of his promise. The passage highlights the importance of community and family support, and how God's care often comes through the actions of others. It reassures readers of the faithfulness and provision that can be found in human relationships when guided by divine principles.
