עירובין ד׳:י׳ - ד׳:י״א

מי שיצא –[a person who left] from his city that the people of city sent him to bring to them an Eruv [with a piece of bread] in order that they would be able to walk on the morrow to a city that is making an Eruv for it that is near to them two Sabbath limits and one can walk from one to the other through [the use of] an Eruv.

והחזירו חברו – for he said to him, it is a period of heat, or a period of cold.

הוא מותר לילך – on the next day to the same other city for since he took possession of the path in order to purchase a Sabbath resting place at the end of two-thousand cubits away from the city, he is like a poor person who states that “my Sabbath resting place is in a certain place,” and he has acquired there his resting place.

וכל בני עירו אסורין – for they did not take possession of the path and they have nothing other than two-thousand cubits in every direction from their city.

רמ"א וכו'- Rabbi Meir doubts whether he is poor since he left from his house and took possession of the path or perhaps because he was able to make an Eruv with bread or he didn’t make an Eruv, he is not a poor man; therefore he is an ass driver [or] a camel driver, who does not have two-thousand cubits from his city in every direction lest his Sabbath resting place is in the place where he was walking to bring there the Eruv at the end of the two-thousand [cubits] from his city and at the end of the two-thousand [cubits] from his city, he also did not acquire two-thousand [cubits] towards the side of another city – lest he did not acquire a Sabbath resting place other than in his own home, but the Halakha is according to Rabbi Yehuda.

אפילו אמה אחת לא יכנס – and he doesn’t have anything other than four cubits from here and four cubits from there, and even though his four cubits is enclosed within the [Sabbath] limits of the city, we do not say that since he arrived, he arrived, for he holds that the enclosure of Sabbath limits isn’t anything.

שתים יכנס – Rabbi Eliezer, according to his reasoning who said, that he is in their middle, for at the end of the two-thousand [cubits], he has four cubits – two from this side within the [Sabbath] limit and two from that side at the end of the [Sabbath] limit; therefore, if he would stand in the second cubit, he could enter for the enclosure/absorption of [Sabbath] limits matters, but the Halakha is not according to Rabbi Eliezer.

מי שהחשיך – that he was coming from the path and it became dark for him outside the [Sabbath] limits.

לא יכנס – because he did not acquire a Sabbath resting place in his place because he did not reveal his intention that he wanted to acquire a Sabbath resting place in his place. But in the city, he did not acquire a Sabbath resting place because between him and the city there is more than two-thousand cubits, therefore, he has nothing other than four cubits according to the law of “he who went outside the Sabbath limits.”

עד ט"ו אמה – not exactly, for the same law applies a little bit less or a little bit more. But there are those who interpret fifteen [cubits] exactly, and I don’t know how to reconcile this well.

המשוחות – those who measure the [Sabbath] limits (i.e., the surveyors) for the cities and make a sign at the end of the [Sabbath] limit, they do not measure to make the sign of two-thousand exactly but mark within the limits in order to allow for mistakes (see Talmud Eruvin 52b) who do not recognize the sign and sometimes they go out further than it, and they are not paying attention to it; because of this, it is was customary always to contract within the two-thousand, so that it would be that these fifteen cubits are within the [Sabbath] limits and since this individual was the victim of an accident, we permit him to enter and we are not stringent with him, for just as we are stringent with someone who left outside of the [Sabbath] limits and there, he had to be careful to pay attention that he should not leave, but the Halakha is not according to Rabbi Shimon.
