.ה In the Right Time

ואם חוזר בו נאסף בזמנו כאברהם אבינו שנאמר והומכו ככל יקפצון כאברהם יצחק ויעקב דכתיב בהו בכל מכל כל

I am somewhat puzzled as to the exact meaning of נאסף בזמנו. Does it mean they will die in their proper time? If so, that is slightly troubling per the well-known רש"י in next week's  פרשה (כ"ה:כ"ט) which states that אברהם passed 5 years before his time so as not to see his grandchild stray from the path. Regarding יעקב as well, we are told that years were taken off his life. What, then, is the meaning?

:מח One Night

או שהיתה לה חצר בדרך ונכנסה עמו ללין

ונכנסה עמו. עם בעלה ללון כשאר לינה בדרך בעלמא ולא לשם נשואין:

Throughout the daf, the gemara always uses the term ללין and רש"י consistently uses ללון instead. This is somewhat puzzling considering רש"י's own comment to בראשית כ"ד:כ"ג in which he states that ללין connotes one night's stay whereas ללון implies many nights. In the cases with which our gemara is dealing, it seems to be pretty clear we are talking about just one night. Why would רש"י change the text?

 

.ג Every Dog has his... Time

מִשְׁמָרָה רִאשׁוֹנָה חֲמוֹר נוֹעֵר, שְׁנִיָּה כְּלָבִים צוֹעֲקִים, שְׁלִישִׁית, תִּינוֹק יוֹנֵק מִשְּׁדֵי אִמּוֹ, וְאִשָּׁה מְסַפֶּרֶת עִם בַּעֲלָהּ... חָשֵׁיב סוֹף מִשְׁמָרָה רִאשׁוֹנָה, וּתְחִלַּת מִשְׁמָרָה אַחֲרוֹנָה, וְאֶמְצָעִית דְּאֶמְצָעִיתָא.

It comes out, according to this approach that the time for dogs to bark (or scream) is exactly at חצות as that would be the the middle of the middle משמרה. Perhaps this lends another interpretation to the פסוק of וּלְכֹל בְּנֵי יִשְׂרָאֵל לֹא יֶחֱרַץ־כֶּלֶב לְשֹׁנוֹ - שמות י"א:י"ז. Perhaps this was just exactly the time that the dogs made lots of noise and nevertheless, everything was peaceful in the Jews' neighbourhood.
