פירוש על בבא קמא 3:7

It lets us know that the chopper, if he damages, he is obligated, whether he is on his own property or if he is not on his own property, and whether he damages in a place where many are found, and this is a public domain, or in a place where the many are not found, and this is a private domain.

המבקע – wood

[If] a man was splitting wood in the private domain and injured anyone in the public domain, or if he was in the public domain and injured anyone in the private domain, or if he was in a private domain and injured anyone in another private domain, he is liable. Mishnah seven teaches that if a person while chopping wood damages another person, no matter where the chopping is done and no matter where the damages are done, the wood-chopper is liable.

והזיק ברשות היחיד – of others.

Questions for Further Thought:
• Based on mishnah seven, would you think a person would be liable if while chopping wood on his own property he damages someone who has entered his property?

ברשות היחיד – his own.

והזיק ברשות היחיד – of others,

חייב – he is liable [for damages caused] and even though he did it in his domain for many are not found there since we would say that he should have taken deliberation. Even as such, he is liable.
