Needless to say, that is exactly what Ruth did. Even after Naomi encouraged her to go back home, Ruth insisted. She gleaned the fields in order to provide and take care of Naomi and herself.
Basically she put her mother-in-law's needs above her own, and that is why we marvel at the story of Ruth.
She found herself in "Holland" after the loss of her husband, and the moment she landed, she got busy attending to the needs of others.
Do you know a modern-day Ruth? I do!
