And these are [the ones] who are coerced to divorce: a leper, one afflicted with an offensive nasal smell, one who gathers, one who mines copper, and a tanner —- whether they had them before they were married, or they came about after they were married. Concerning all of them, R’ Meir said: Even if he had stipulated with her, she can say: “I thought I would be able to endure it, but now I cannot endure it.” The Sages, however, say: She must endure it against her will, except a leper, because she causes his flesh to decay.  It once happened in Sidon that a tanner died, and he had a brother [who was also] a tanner. The Sages said: She can say: “Your brother I could endure, but you I cannot endure.”
