What if a person has a dream that he is ostracized? Rav Yosef believes that he must find ten scholars of Torah to dissolve the ostracism. Other rabbis argue that one might not have many Torah scholars in a given town, and they suggest that people who read Torah, or those who have learned Mishna, or ten people on the street, or even just three people will serve the same purpose. They recognize that every dream is a mixture of truth and idle matter, but just in case the ostracism was real, that ostracism must be dissolved.
We learn about Ravina's wife. She made a vow that she wanted her husband to nullify, but he did not do so that same day. She asked if he would act as her agent with the court to nullify her vow. Ravina took this question to Rav Ashi. We learn three halachot through this narrative:
- a husband can act as his wife's agent when she regrets an action
- a Sage cannot dissolve a vow in the same location as his teacher, and
- a court of three people can dissolve a vow, but only if they were sitting already for a different purpose
