The answer is: Kinsman of Elimelech

Ruth 2:1

Boaz is a fascinating figure in the Book of Ruth and is often viewed as the ideal model of kindness and integrity. As a kinsman of Elimelech, Ruth's deceased father-in-law, Boaz had a legal and social responsibility to care for Ruth and Naomi, thereby ensuring their well-being. This obligation stems from the custom of levirate marriage, which meant that a relative should marry a widow to carry on the family line, maintaining the clan's inheritance within the family.

What’s especially intriguing is how Boaz embodies the values of justice and generosity. In Ruth 2:1, he is described not only as "a mighty man of wealth" but also as someone who extends compassion towards Ruth, a Moabite woman. This juxtaposition highlights a broader theme of inclusivity present throughout the book. Although Ruth was from a different background—one often viewed with disdain by the Israelites—Boaz establishes a bridge of understanding and love, shaping what could be seen as the very roots of a more expansive view of community.

As trivia, it’s interesting to note that Boaz's name means "in him is strength," paralleling his character traits. Plus, in a literary twist, Boaz and Ruth's union eventually leads to a lineage that will extend to King David! And, according to the genealogy method found in Matthew’s Gospel, this too ultimately ties to Jesus, showcasing how one act of kindness and a sense of duty forms part of this grand tapestry of faith shaping continued history.
