Rava said that the word "se - sheep" in the Torah comes to exclude mixed breeds. To what halakha was this statement referring to? If one took upon oneself to bring a sacrifice of a burnt offering ("harei alai olah"), designated a bull and then someone stole it, does the thief have to replace it with a bull or can the thief replace it with a sheep or bird as the original owner can give one of those as an offering to fulfill their commitment? If a thief did not completely sell the animal or did not do a proper slaughter, there is no four/five payment. There are four different opinions regarding what part of the animal the thief would leave for him/herself which would render the animal still partially owned by the thief, thereby exempting the thief from the four/five payment. There are contradictory braitot regarding partners who stole and animal and one of them sold it - one says the one who sold it is liable and the other, exempt. How does Rav Nachman resolve this contradiction? Rav Yirmia and Rav Papa ask more questions regarding cases of partial sales of the animals. Their questions are left unanswered.
