Why does the Torah write "Im Kofer Yushas comes"?
Rashi: This is one of three cases where "Im" is obligatory. 1
Ramban: Because, since Kofer is a Kaparah (like Korbanos), should he opt not to go to Beis-Din, they will not obligate him to pay. 2
Seforno: Because he is only Chayav to pay Kofer in the event that witnesses testify that the Mu'ad gored.
Targum Onkelos and Targum Yonasan: Following on from the previous Pasuk, the Torah is simply stating that, in the event that Beis-Din obligate him to pay Kofer, then he pays and is Patur from Misah.
Bava Kama, 43b: To include where the ox intended to gore an animal, but it inadvertently gored a human-being, in the Din of Kofer. 3
Oznayim la'Torah: Refer to 21:22:156:2.
Refer to 20:22:1:1** where, in the name of the Mechilta, Rashi cited three cases, and this was not among them? See also Torah Temimah, note 327. Citing R. Yishmael, the Mechilta exclaims 'Come and see the extent of Hakadosh-Baruch-Hu's compassion on human-beings, when a man can redeem himself from Misah bi'Yedei Shamayim with money!'
Ramban: Even if he does go to Beis-Din, and Beis-Din obligate him to pay, they will not coerce him to pay by taking a security until he pays (as they do in the case of someone who is Chayav a Chatas). Targum Yonasan however, refers to the payment as a K'nas (a fine), in which case it seems that Beis-Din will force him to pay.
Even though the ox is not stoned. See Torah Temimah, note 227.
If a Shor Mu'ad belonging to two partners gored another ox with two hundred Zuz, how much must each partner pay?
Bava Kama, 40a: Each partner must pay two hundred Zuz. 1
Since Kofer is equivalent to Kaparah, and there is no such thing as half a Kaparah. See Torah Temimah, note 224.
The value of whose "Nefesh" must he pay?
Rashi: This is a Machlokes Tana'im in the Mechilta: According to R. Yishmael - he pays the value of the Nizak; 1 according to R. Akiva - he pays his own value.
Which we learn from a Gezeirah Shavah "Comes" "Comes" from Ka'asher Yushas comes Ba'al ha'Ishah" - Pasuk 22, with reference to the value of the Nizak (the fetuses). See also Ba'al ha'Turim. See Torah Temimah, note 229.
At which point does the owner of the ox become Chayav to pay Kofer?
Bava Kama, 42b: Based on the juxtaposition of "Im Kofer" to "ve'Gam Be'alav Yumas", Kofer only becomes payable after the ox has died. See Torah Temimah, note 226.
What are the implications of the word "ke'Chol asher Yushas Comes"?
Bava Kama 26a: It implies "Comes", 've'Lo al ha'Adam'. To teach us that a person is not Chayav to pay Kofer (in addition to being sentenced to death). 1
Like the ox. See Tosfos there. See also Torah Temimah, note 230, citing Rashi, that this refers to someone who killed and there were no witnesses, who is therefore not Chayav Misah.
