The answer is: Didn't want to spoil inheritance

Ruth 4:5-6

In the Book of Ruth, we encounter an intriguing scenario that boils down to the cultural dynamics of ancient Israel. The kinsman, referred to as the "redeemer," ultimately declines to marry Ruth—the widowed Moabite woman. His reluctance circles back to inheritance issues, hinting at an intricate tapestry of family loyalty and property rights.

When this kinsman expresses concern about jeopardizing his own inheritance, it reflects societal norms where preserving land ownership was paramount. In biblical times, land assignments were viewed as sacred, tied deeply to family heritage. Thus, the kinsman wisely recognizes that marrying Ruth could dilute his existing inheritance, affecting not only him but potential descendants.

What’s fascinating is how this situation draws on the deeper themes of loyalty and redemption. Boaz steps in as the heroic redeemer—a figure embodying love, courage, and responsibility. His willingness not only to marry Ruth but also to assure her a legacy showcases an immense act of compassion that overrides the technicalities of law. He fulfills a unique role in ensuring Ruth, a foreigner, finds acceptance and security within Israel’s community.

Additionally, when Boa marries Ruth, their lineage is pivotal, ultimately leading to King David—and by extension, this lineage introduces a hope that extends into the patterns of justice, love, and belonging that continue to resonate across generations. How amazing is it to witness a story that begins with despair transform into hope!
