2a

{Yoma 77b continues}
to enter {the water} to come to the lecture, and to return.
Abaye said to him: Now coming, the performed a mitzvah. To return, what mitzvah are they performing?
He said to him: So that they do not stumble in the future. For if we did not permit them to return to their homes, they would not come for the mitzvah.

Rav Yehuda and Rav Shmuel bar Yehuda {Bach: bar Rav} were standing on the bank of the Papa river {our gemara: emend to Nehar Perat = Euphrates} at the passage to Chatzdad. And Rami bar Papa was on the other side. He raised his voice and said: May one cross {the river, getting wet} to come before the Rabbis {Rav Yehuda and Rav Shmuel bar Yehuda} to ask a halachic question?
Rav Yehuda said: Rav and Shmuel both say that one may cross, provided that one does not draw away one's hands from the skirts of one's robe.

Some say {another version}:
Rav Yehuda and Rav Shmuel bar Yehuda {Bach: bar Rav}: we learnt it {in a brayta}: provided that one does not draw away one's hands from the skirts of one's robe.

{Yoma 78a}
This is fine on Yom Kippur, when he does not have shoes on his feet, he can cross in water. On Shabbat, where there are shoes {and he might come to carry them}, what is there to say?
Rabbi Nechemia the in-law of the house of the Nasi said: I saw Rabbi Ami and Rabbi Assi who crossed while wearing their shoes.
This is fine in terms of shoes. Sandals, what? And we conclude that sandals, lechatchila {ab initio} not.

Rav Yehuda {our gemara: Yehuda bar Gerogros} taught: It is forbidden to sit on clay {our gemara: on mud} on Yom Kippur.
Rabbi Yehoshua ben Levi said: This is speaking of moist clay {/mud}.
Abaye said: And it was moist enough to make someone else wet.

Rav Yehuda said: It is permitted to cool off with fruits.
Rav Yehuda would cool off with a gourd.
Rabba would cool off with a baby.
Rava would cool off with a silver cup.

Rava said: A full silver cup is fobidden. Partly full is permitted. One of earthenware, whether full or partly full is forbidden. What is the reason? It exudes {water from within}.

Rav Ashi said: Even a partially full silver cup is forbidden. What is the reason? He will come to azdarbuyei.
To explain: lets he shake it and the water within sprinkles on his flesh.

Zeira bar Chama the innkeeper of Rabbi Yehoshua ben Levi, of Rabbi Ami, of Rabbi Assi, and of the Rabbis of Caesarea said to Yosef the son of Rabbi Yehoshua ben Levi: Son who has learned much Torah {our gemara: Son of the lion}, come and I will tell you an excellent thing that your father did. Erev Tish'a beAv, they would bring him a cloth, and he would soak in water, and he would use it to wipe his face, hands and feet. The next day {=the 9th of Av} he would pass it over his eyes without concern. On erev Yom Kippur he would soak it in water and make it like dried vessels {/clothing = he would let it dry overnight}. The next day {=Yom Kippur} he would pass it over his eyes without concern.

And so too, when Rabba bar Mari came {from Eretz Yisrael}, he said: Rabbi Yehoshua ben Levi had a cloth. On erev Yom Kippur he would soak it in water and then made it like dried vessels {=he let it dry overnight}. The next day he would pass it over his eyed without concern.

And we conclude {that the version is different and} that on erev tish'a beAv he would soak it and make it like dried vessels, and on erev Yom Kippur he would wipe his {wet} hands and feet and on the next day would pass it over his eyes without concern, but he would not soak it in water initially, for concern for squeezing out when he passed it over his eyes.
And so is the halacha.

{Yoma 78b}
It was a question to them: May one go out with rubber sandals on Yom Kippur?
Rabbi Yitzchak bar Nachmani stood on his feet and declared: I saw Rabbi Yehoshua ben Levi go out with rubber sandals on Yom Kippur. I said to him: On a {regular} public fast day, what? He said to me: there is no difference.

Rabba bar bar Chana said: I saw Rabbi Eleazar go out on a public fast day with rubber sandals. I said to him: On Yom Kippur, what? He said to me: there is no difference.

Rav Yehuda would go out with dehitnei. {Rashi: a kind of rubber}
Abaye would go out with dehutzei. {Rashi: and sandal of palm fronds}
Rava would go out with divlei. {something of a thick viscous mass?}
