(Mishnah - R. Meir): If Reuven told a Shali'ach 'give this Get to my wife', or 'to my slave', in either case Reuven can retract;

Chachamim say, [he can retract from] Gitei Nashim, but not from Shichrurei Avadim;

This is because Zachin l'Adam she'Lo Befanav (we may do something beneficial for someone in his absence), v'Ein Chavin Lo Ela b'Fanav (we may do something detrimental to him only in front of him. A Shali'ach can receive a Get on behalf of a slave, for freedom is beneficial,) for if [the master] wants, he need not feed his slave. [One cannot accept a Get for a woman, for divorce is detrimental, for if a husband] does not want to feed his wife, he is not allowed.

R. Meir (to Chachamim): [Also freedom is detrimental. If the master is a Kohen,] he disqualifies his slave from eating Terumah, just like [a Kohen who divorces] disqualifies his wife!

Chachamim: That is because he is his [master's] acquisition. (This will be explained.)

If Reuven said 'give this Get to my wife, and this Get Shichrur to my slave', and Reuven died, we do not give them after death;

[If he said] 'give 100 Zuz to Ploni', and he died, we give it after death.

(Gemara) Question: Everywhere, you say 'give' is like 'bring' (he does not intend that the Shali'ach acquire for the recipient), and here you say that 'give' is like 'Zechi' (acquire for! All agree that if it is beneficial for the recipient, he cannot retract.)

Answer: Our Mishnah discusses one who said 'Zeche this Get for my wife', 'Zeche this Get Shichrur for my slave.'

Support: The wording of our Mishnah supports this - 'because Zachin l'Adam she'Lo Befanav, v'Ein Chavin l'Adam Ela b'Fanav.'

R. Meir says that it is Zechus both for [a wife] and [a slave]. Rabanan say that it is Zechus for a slave but Chov for a wife.

Question (R. Chiyah bar Ba citing R. Yochanan): Exert yourself [and you will find the answer]! If he was the slave of an officer (he is financed liberally), it is a Chov for the slave!

Question (Talmidim citing R. Yochanan): Exert yourself [and you will find the answer]! If she was the wife of a leper, it is a Zechus for the woman!

Answer (to both questions): One who sells his slave without the slave's Da'as, perhaps he is not sold?! (Freedom is beneficial; losing the Heter to eat Terumah is Chov. Since the master can disqualify him from Terumah without Shichrur, this is not considered Chov; freedom is pure Zechus. And one who divorces his wife [via a Shali'ach] a without her knowledge, is she divorced?! (Since he has no other way to make her lose being fed, divorce is not pure Zechus, even for a leper's wife.)

(Mishnah): Because he is his acquisition.

(R. Avin): [Chachamim answered that] he is his acquisition - can he not disqualify him from Terumah [even without Shichrur?! Therefore, this is not a reason to consider freedom to be a Chov. We explained this like ME'OR HA'SIMCHAH.]
