The answer is: She had looked after Naomi

Ruth 2:10-11

In the book of Ruth, Boaz’s generosity towards Ruth is rooted deeply in his awareness of her character and past actions. Ruth wasn't just looking for leftovers in the fields physically; she was also showing immense loyalty and love towards her mother-in-law, Naomi, who had suffered grievously after losing her husband and sons. This determination to care for Naomi brings Ruth into Boaz's favor.

Gleaning was a social safety net in ancient Israel, rooted in the commandment for harvesters to leave some grain behind for the poor and marginalized. It's fascinating how Boaz extends kindness beyond mere obligation; he actively encourages Ruth while letting her collect as much as she needs. This act of kindness also speaks to the setting of the time—a time when societal systems didn't always look kindly on women, especially widows.

Boaz even goes the extra mile by advising his workers to help her by dropping extra bundles—an interesting note here is that it emphasizes community responsibility for those in need. This mirrors many themes in the Bible where the concepts of charity and support are woven throughout.

Interestingly, Ruth eventually becomes the great-grandmother of King David, placing her and Boaz at the very heart of Biblical history. This redemptive story showcases the power of caring relationships and God’s providence, guiding both ordinary and extraordinary lives toward significant outcomes.
