(Mishnah): Property of Bnei Bris.

This excludes a Yisrael's ox that gored a Nochri's ox.

(Mishnah): Distinctive property.

This excludes Hefker.

(Mishnah): Except for premises exclusively to the damager.

There he is exempt, but [payment for damage] applies in [joint] premises of the victim and the damager.

Question (R. Yirmeyah): Had the Tana taught 'except for premises exclusively to the damager' and no more, I would have said that the same applies to a joint Chatzer [of the damager and victim], and a Chatzer that is not of both of them - he is liable. Why did the Tana say [that payment for damage] applies in the premises of the victim and the damager?

Answer: Rather, this refers to a Shomer Chinam, borrower, Shomer Sachar and a renter.

Question (R. Yosi): Since the Tana taught 'except for premises exclusively to the damager', don't we know that it applies in the premises of the victim and the damager? Why did he teach 'it applies in the premises of the victim and the damager'?

Answer: Rather, this excludes a Chatzer that is not of both of them (rather, of a third party).
