Which book of the Bible is specifically noted for its portrayal of a kinsman-redeemer?

The book noted for its portrayal of a kinsman-redeemer is Ruth. This short book from the Old Testament tells the story of Ruth, a Moabite woman, and her relationship with her Jewish mother-in-law, Naomi.

In the narrative, Ruth's character embodies loyalty and devotion, as she chooses to remain with Naomi after the death of their husbands. When Naomi seeks to secure a future for herself and Ruth, the concept of the kinsman-redeemer is brought to the forefront through Boaz, who is a relative of Naomi's deceased husband. Boaz's willingness to redeem Ruth not only showcases his adherence to the customs and laws of the time but also serves as a metaphor for God's providential care and redemption.
