פירוש על קידושין 35:6

The baraita above implies that a male slave goes out upon his master’s death but a female slave does not. But this clearly contradicts the mishnah which teaches that any way that he goes out, she does too. The only difference is that she also goes out with “signs” meaning she has hit puberty.
Rav Sheshet solves the contradiction by positing that the baraita refers to a case where the master designated, i.e. married off, the slave girl to his son. This seems to have been the point of the sale in the first place. However, as we shall see, this is not an easy solution.
