A braita is brought that lists damages that one causes to someone else and yet is not obligated by the hands of men but is obligated by the hands of God. The gemara then questions why the list is limited to these four and doesn’t mention others that have the same law. A distinction is made between the cases listed here as they are cases where one may have thought one wouldn’t even be obligated by God and therefore they are different than the other cases brought. The next cases in the mishna are analyzed: if the gate opens at night – what is the case? What type of wall? How did it break? IF the robber takes the animal, he is responsible? Isn’t this obvious? The gemara gives 2 explanations what the case is and why it needed to be stated.
