The answer is: 1 ephah of barley

Ruth 2:17

Ruth’s first day of gleaning is quite significant, not just for its material abundance but for the emerging themes of hope and resilience. Gleaning, the act of collecting leftover crops from a harvest, was a practice rooted in giving the less fortunate an opportunity to provide for themselves (as outlined in Leviticus 19:9-10). This scene underlines Ruth's determination and avalanche of faith during a challenging time, navigating her new life in Bethlehem after leaving Moab.

Now, let's talk about that impressive amount—1 ephah, which is about 22 litres or roughly 3/5 of a bushel. It’s quite the haul for a single day's labor! This wouldn't just feed her and Naomi, but could also symbolize Ruth's drive to carve out a future amidst hardship. When placed in context, this yield allows us to appreciate the abundance found in kindness and community support—two powerful themes resurging throughout the narrative.

In addition, Ruth's gleaning also anticipates her astonishing relationship with Boaz. For many readers, this moment resonates with prophetic echoes throughout the Bible where unexpected blessings come from humble beginnings. Ruth, a Moabite woman, fittingly reflects God’s wider vision for humanity. Her story mutedly challenges ethnic boundaries, suggesting that everyone, regardless of background, is set apart for divine purpose—transforming not only her own fate but also bringing nourishment and blessing to others.
