he returns to the first perek. If in the middle of a perek he returns to the beginning of the perek. Between two instances of the same writing {occurence of a word or phrase}, he returns to the first instance of the writing.

Rabbi Yochanan said to him: We are only talking about where he has not yet reached limaan yirbu yemeichem. But if he has already reached limaan yirbu yemeichem he can assume that he has taken his regular course {and said it correctly}.


MISHNAH.
WORKMEN MAY RECITE [THE SHEMA'] ON THE TOP OF A TREE
OR THE TOP OF A SCAFFOLDING,
A THING THEY ARE NOT ALLOWED TO DO IN THE CASE OF THE TEFILLAH.

Gemara:
The Sages learnt {in a brayta}: Workmen may recite [the Shema'] on the top of a tree or on the top of a scaffolding, and they may say the tefillah, on the top of an olive tree and the top of a fig tree, but from all other trees they must come down to the ground before saying the tefillah, and the employer must in any case come down before saying the tefillah, since his {=their} mind is not settled {because of a fear of falling}.

Yerushalmi: Why say specifically at the top of an olive tree and on top of a fig tree?
Rabbi Abba and Rabbi Simone both say: because their bother is a lot {presumably since they are high it is difficult to descend and ascend}.

Mari the son of the daughter of Shmuel asked Rava: we learn in the Mishna "workmen may recite [the Shema'] on the top of a tree or on the top of a scaffolding" which implies that you don't need intent. Contrast with this: Rabbi Shimon ben Yochai says: one who reads the Shema needs to direct his heart ={have intent} as it states Shema Yisrael {Hear O Israel} and later in, Dvarim 27:9:

ט וַיְדַבֵּר מֹשֶׁה וְהַכֹּהֲנִים הַלְוִיִּם, אֶל כָּל-יִשְׂרָאֵל לֵאמֹר: הַסְכֵּת וּשְׁמַע, יִשְׂרָאֵל, הַיּוֹם הַזֶּה נִהְיֵיתָ לְעָם, לַיהוָה אֱלֹהֶיךָ.

9 And Moses and the priests the Levites spoke unto all Israel, saying: 'Pay attention, and hear, O Israel; this day thou art become a people unto the LORD thy God.

Just as there it is with paying attention, so too here with paying attention.
He {Rava} was silent.
He said: have you heard any {saying} on this?
He said to him: so said Rabbi Yochanan {we have Rav Sheshet}: they stop their work and read.
But we learnt {in a brayta}: Bet Hillel say: they involve themselves in their work and read.
It is not a question. Here {Rabbi Yochanan, where intent is required} in the first perek, here in the second perek.

This is an answer [according to the opinion of Rabbi Yochanan...]
