Mishnayos Bava Kamma Perek 5 Mishnah 5

One who digs part of a pit on private property and opens its entrance in the public domain, or digs a pit in the public domain and opens its entrance on private property, or digs a pit on private property and opens its entrance on another person’s private property, is liable for damage caused by the pit in each case. In the case of one who digs a pit in the public domain and an ox or a donkey fell into it, he is liable. The halakha is the same for one who digs either a pit; a ditch, which is narrow and long; or a cave, which is rectangular and roofed; trenches and water channels. In all these cases he is liable. If so, why is the verse stated as referring to a pit, as it states: “And if a man shall open a pit” (Exodus 21:33)? To teach that just as a pit that has sufficient depth to cause death when falling into it is at least ten handbreadths deep, so too, any other excavations that have sufficient depth to cause death may be no less than ten handbreadths. If any of the types of excavations were less than ten handbreadths deep, and an ox or a donkey fell into one of them and died, the digger of the excavation is exempt. But if it was injured in it, not killed, he is liable to pay damages.
