It's possible you're thinking of another story. Could you provide more context or details?
Perhaps you're thinking of:
* The story of Samson: Samson's wife, Delilah, betrayed him by cutting his hair, which was the source of his strength. However, this story doesn't involve a mill.
* The story of Ruth: Ruth, a Moabite woman, helped her mother-in-law Naomi by gleaning grain in the fields. This story doesn't involve a mill either.
Please provide more information so I can help you understand the story you're looking for.
