The answer is: She had looked after Naomi

Ruth 2:10-11

In the book of Ruth, Boaz's decision to allow Ruth to glean in his fields speaks volumes about kindness and community ties. The culture of gleaning, which allowed the marginalized to gather leftover grain from harvests, highlights the layers of social responsibility woven into the fabric of ancient Israelite society. By letting Ruth glean, Boaz not only acknowledges her loyalty to Naomi but also demonstrates a deeply righteous act of generosity.

Now here's an interesting tidbit: Boaz’s compassion mirrors the law of Leviticus, which commanded owners to leave some harvest for the poor and foreigner (Leviticus 19:9-10). This isn’t just about sharing resources; it’s a reflection of God's broader call to justice and support for those in need. Remember, Ruth was a Moabite, a nationality often despised by the Israelites. But Boaz sees beyond prejudices and recognizes her efforts—he’s an early connector of inclusiveness and care in a community setting.

The echoes of this story, particularly Ruth's loyalty and daring to step outside societal norms, invite debates around loyalty, kinship, and the risks of love. Her journey provides a powerful narrative that shows how acts of kindness can lead to transforming destinies. Plus, isn’t it romantic how Ruth, a foreigner with a heart of devotion, finds favor in Boaz's eyes? This blossoming relationship carries rippling significance that goes beyond their time—contributions to the lineage of David. That’s one for the historians to chew on!
