When we first started reading about Rut, I was surprised at her character. It is shocking that the woman from Moab, outside of the Jewish people, would be the one who is kind and moral. We see from Naomi and Alemelach were not. From what we see, they were wealthy important people, but instead of staying in a time where they are needed, they leave. We see that although Boaz is not a bad person, he doesn't reach out and try to be better. When he heard that his realative, Naomi, was back, he didn't go see if she was ok, ask if she needed anything, and offer his help. Instead he sat around and let Rut glean in his field when she came to him.
Rut on the other hand, does everything she can to be better. She gives up her entire life and hope for a future to go with her widowed mother-in-law to a place where she had never been. Because of this move, she left everything behind. She left her family, customs, nation, religion, and home, so she came be with her mother-in-law when she was having a hard time. Even though Naomi starts ignoring her, she stays and does everything she can to help. Rut makes sure Naomi has everything she needs, even though it is no her job. It is no wonder why David HaMelech comes from such a strong, courageous woman.
