פירוש על קידושין 41:17

The Talmud resolves Abaye’s difficulty by saying that the midrash refers only to houses in villages and ancestral fields.
But again, there is a problem, same as above. We have a verse that explicitly teaches that houses in villages have the same rule as ancestral fields. So why would we need a midrash to teach that.

The Talmud solves this by referring to a statement made in another context—that the nearest relative has the first obligation to redeem the house in the village. That is what this midrash teaches. But neither midrash need be read as teaching that houses in walled cities can be redeemed by relatives.
