Rif Eruvin 27a {{Eruvin 82a continues ... 82b}


{Eruvin 82a continues}
BEGIN PEREK EIGHT - keitzad mishtatfin
How do we make a shittuf for {an eruv of} tehum {such that many people can extend their Shabbat boundary}?
He sets down the cask and he says, "This is for all the people on my town, for anyone who will go to a house of mourning or to a house of feasting." And anyone who accepted during the day – permitted. After nightfall – prohibited, for one may not make an eruv after nightfall.

Rav Yosef said: We only make an eruv {of techum} to enable performance of a mitzvah {precept}.
What is this {statement of Rav Yosef} informing us?! It is a Mishna: "for anyone who will go to a house of mourning or to a house of feasting." I would have thought that mention was made of that which was usual {and these are just given as common examples of why one would make a eruv of techum}. Therefore it {=Rav Yosef's statement} informs that specifically to
enable performance of a mitzvah.

Rav Ashi said: A child of age six may go out by the eruv {of techum} of his mother.
This implies that greater than six, he needs to make his own eruv.

{Eruvin 82b}
The Sages learnt {in a brayta}: A man may make an eruv via minor his son or daughter, or via his Canaanite manservant or maidservant, with or without their consent. But he may not make an eruv via his adult son of daughter, nor via his Israelite manservant or maidservant, nor via his wife, unless by their consent.

And what is the quantity? Food of two meals for each one.
His food on weekdays and not on the Shabbat. These are the words of Rabbi Meir.
Rabbi Yehuda says: On the Shabbat and not on the weekdays.
And this one and this one intended to be lenient.

Rabbi Yohanan ben Beroka says: From a loaf {purchased for a pundion - a monetary value worth 1/48 of a sela'} when four se'ahs {of wheat sell} for a sela' {another monetary unit}.
{Since there are 6 kav in a se`ah, four se`ah = 24 kav; Thus this loaf of bread weighs half a kav.}
Rabbi Shimon says: Two thirds of a loaf when three {loaves are made} from a kav. {Thus, 2/9 of a kav}
Half of it {the loaf of Rabbi Yochanan ben Beroka and Rabbi Shimon} for a leprous house {if one stays in there long enough to consume it} and half of its half to render the body unfit {if it is ritually unclean}.
{Note: Only half a loaf for these two laws because the loaf under discussion was food for two meals.}

One {brayta} taught {tana}: Their views are almost identical.
Whose views? If you say the views of Rabbi Yochanan ben Beroka [and Rabbi Shimon, are they really comparable? For according to Rabbi Yochanan ben Beroka, there are four meals to a kav.
