Why does the Torah write "ve'Lo Yishmerenu" by Mu'ad and not by Tam?
Ramban #1: According to the opinion that a Mu'ad requires a better guarding than a Tam, 1 it teaches us that the minimal Shemirah that will suffice for a Tam will not suffice for a Mu'ad.
Ramban #2: According to those who hold that both require only a minimal Shemirah, it is to inform us that, since, even after it became a Mu'ad, the owner still failed to guard it, he is obligated to pay full damages.
See Rav Chavel's footnotes.
Why does the Torah use the double Lashon "Shalem Yeshalem"?
Bava Kama, 34b: To teach us that, even though the Mazik shares in Sh'vach Neveilah, 1 this will not aply if half the Sh'vach comes to more than the value of the damage.
What if the Ganav steals an animal other than an ox or a lamb and Shechts it? Is he also obligated to pay Arba'ah va'Chamishah?
Bava Kama, 62b: No!
See Torah Temimah, note 290.
Why does the Torah insert the word "O"?
Bava Kama, 77a: To include Kil'ayim (the baby of a sheep and a goat) in the Din of Arba'ah va'Chamishah. 1
Mechilta: To teach us that if the Ganav steals both a Shor and a Seh and Shechts or sells them, he is Chayav for each one. 2
Is the owner permitted to pay money instead of an ox?
Mechilta: Yes! We learn a Gezeirah Shavah "ve'ha'Meis Yih'yeh lo" "ve'ha'Meis Yih'yeh lo" from Pasuk 34 - Just as there the Torah permits the owner of the pit to pay money, so too here; and just as here the Torah permits him to pay an ox, so too there.
Why does the Torah add the suffix "Vav' in "u'Tervacho O Mecharo"?
Bava Kama, 78b: To include where Reuven, without Shimon's knowledge, Shechted or sold an animal that he shared with Shimon, or where he Shechted or sold an animal that he and Simon stole. 1
Bava Kama, 71a: To include a Shali'ach
What can we learn from the comparison of Mechirah to Tevichah or of Tevichah to Mechirah?
Bava Kama, 68a: Just as Tevichah is ireversible (permanent), so too must the Mechirah be permanent
Is the Ganav Chayav if he declares (sells) the ox Hekdesh?
Bava Kama, 79a: Yes! 'What difference does it make whether he sells it to a Hedyot or to Hashem?' 1
See Torah Temimah, note 300.
If he only pays double when he steals the animal, why must he pay four or five times when he Shechta or sells it?
Bava Kama, 67b & 68a, according to R. Akiva: Because he becale attatched to the sin. 1
Bava Kama, 67b & 68a, according to Rava: Because he sinned a second time. 2
If the Ganav steals and Shechts or sells an ox belonging to two partners,and confesses to one of them, is he Chayav to pay (half) the K'nas to him?
Bava Kama, 71a: Yes! 'The Torah writes "Chamishah Bakar"
What are the connotations of "ve'ha'Meis Yih'yeh lo"?
Ramban #2: The Neveilah belongs to the Mazik, to include in the payment to the Nizak. 3
QUESTIONS ON RASHI
Rashi writes that "veha'Mes Yihyeh Lo" teaches that the Neveilah belongs to the Nizak and the Mazik pays the balance. Bava Kama 51a expounds this to exclude Pesulei ha'Mukdashim!
Perhaps the verse teaches that the Neveilah belongs to the Nizak, and automatically 1 we infer that Pesulei ha'Mukdashim are excluded! (PF)
Refer to 21:34:2:2*.
Riva left this difficult. Perhaps he holds that "Kol she'Eino Ra'uy l'Bilah Bilah Me'akeves" applies only to Mitzvos, but not to payment of damage. (PF)
