2 If tax collectors took his ass and gave him a different ass; if thieves stole his garment and gave him a different garment, they are his, the owners "despairing" of them. [In all probability the owners "despaired" of them immediately, so that he acquired them with yeush and change of domain.] If one rescued something from a river or from a troop or from robbers, if the owners despaired, they are his. [This, if it is known that they had despaired, saying: "Woe for what I have lost!" But otherwise, they are not his. As to "if thieves stole his garment, etc.", above, which implies that yeush is assumed, this is so in the instance of Jewish robbers. For since Jewish judges say: "Bring witnesses; bring proof," as soon as the robbers take it, he despairs. The other instance, however, is one of gentile robbers, gentile judges judging with "pride, might, and conjecture," without witnesses and proof, so that the one who is robbed does not despair. Accordingly, if we know that the owners have despaired, it is his; if not, not.] Likewise, a swarm of bees [with their king] — if the owners despaired, they are his. R. Yochanan b. B'roka said: A woman or a minor is believed to say: "This swarm came from here," and one may enter his neighbor's field to rescue his swarm; but if he damages [something in doing so], he pays for the damage. But he may not cut off his branch. [If the bees settled on his neighbor's branch, and he fears that if he takes them off one by one, the others will escape, he may not cut off the entire branch, even] with the intention of paying him. R. Yishmael, the son of R. Yochanan b. B'roka, says: He may also cut (the branch) and pay for it. [The halachah is not in accordance with R. Yishmael.]
