בבא קמא ה׳:ג׳ - ה׳:ד׳

היה אביו או בנו – of the owner of the house were in it (i.e., the cistern) and the same law applies for the rest of the people, but [the Mishnah] took a usual incident.

משלם את הכופר – as for example, the [owner of the] animal had been forewarned to cause himself to fall upon on people in cisterns and currently saw herbs in the pit and caused itself to fall into the cistern to eat the herbs and killed a person, that the [owner of the] ox is exempt from the death penalty, for it killed without intention. But the owners [of the ox] pay the ransom, for it includes the ransom even if the animal killed without intention, as we have stated above.

רבי אומר וכו' – And the Halakha is according to Rabbi [Yehuda HaNasi]. Therefore, if [the owner of] the animal led his ox [into the courtyard] with the permission of the owner of house, in an undefined manner, and he didn’t accept upon himself to guard [the animal], the owner of the house is exempt, for he did not accept upon himself watching/proper care. And the one who brings it (i.e., the animal) in is also exempt [from liability] because he brought it (i.e., the animal) in with permission.

שור שהיה מתכוון לחבירו וכו' – since our Mishnah had to teach the “concluding” (actually, the next phrase) part [of the Mishnah] that a person who intended [to strike] his fellow, the first part [of the Mishnah] teaches also regarding an ox that intends [to gore] its fellow [ox], for even if it had intended [to gore] a woman , the [owner of the] ox is exempt from the payment [for the value of] the offspring, for he is not liable for the payment [for the value of] offspring other than of a human being alone.

א"כ משהאשה יולדת משבחת – if so, that this is what we assess just as you said, it is found that he doesn’t give you anything for from when the woman gives birth, her worth is enhanced for her monetary value is less to be sold prior to her giving birth when she is in danger of dying in the pain of childbirth.

היתה שפחה ונשתחררה – meaning to say, when she was freed, she was married to a convert or to a manumitted slave or a female convert is married to one of them , and the husband (who was a freed slave or a convert) passes away, [the owner of the one who caused the damages] is exempt, for the individual who takes possession of the property of the convert who died and he has no heirs has merited, and this comes prior to acquiring what is in his hands. And the same law applies also to an Israelite woman who married a convert, and the convert died, he is exempt, for the value of the offspring goes to the husband, but because an undefined freed woman slave or a female convert are married to a male convert or to a freed slave, for this reason, [the Mishnah] took the language of a maidservant and a female convert.
