Yerushalmi Eruvin 5:6 ירושלמי עירובין ה׳:ו׳

MISHNAH: If somebody was in the East and told his son to make him an eruv in the West, or in the West and told his son to make him an eruv in the East, if there are from his place to his house 2’000 cubits but to his eruv more than this, he is permitted up to his house but forbidden to his eruv¹⁷This refers only to somebody who tells his son shortly before sundown on Friday to make an eruv for him, but he goes in the opposite direction and therefore could not reach the place of his eruv before sundown. Then the eruv is invalid for him, but since he ordered an eruv made he lost the rectangular domain of the town dwellers and now can only move in a circle of radius 2’000 cubits.; if to his eruv 2’000 cubits but to his house more than that, he is permitted up to his eruv but forbidden to his house. If somebody puts his eruv in the complement of the town¹Greek πῆγμα, τό. This expression is used for all structures that are not human dwellings. The pegma of a city wall is a watch tower. The example of the Babylonian Geonim (geonim Harkavi p. 182) is a dove-cote. he did not do anything¹⁸Since this is considered part of the town anyhow.. If he puts it outside the domain¹⁹Not outside the Sabbath domain, since then he could not move outside of 4 cubits, but in the Sabbath domain outside the augmented town. Because he made an eruv, his Sabbath domain is a circle of radius 2’000 centered at the eruv; he loses not only the distances in the direction opposite to that of his eruv but also the rectangular shape of his domain. what he had gained he loses.

HALAKHAH: Paragraph. “If somebody was in the East,” etc. Because of the difficulty did Bar Qappara ask, the East of his son and the West of his son? One understands “if there are from his place to his house 2’000 cubits but to his eruv more than this, he is permitted up to his house but forbidden to his eruv¹⁷This refers only to somebody who tells his son shortly before sundown on Friday to make an eruv for him, but he goes in the opposite direction and therefore could not reach the place of his eruv before sundown. Then the eruv is invalid for him, but since he ordered an eruv made he lost the rectangular domain of the town dwellers and now can only move in a circle of radius 2’000 cubits..” “If to his eruv be 2’000 cubits but to his house more than that, he is permitted up to his eruv but forbidden to his house”¹⁴²If one read the Mishnah as him being in one side of the town and his son in the other side it would be impossible for his house to be farther away than his eruv. Therefore one has to read the Mishnah as “him to the East of his son and the West of his son”. Babli 60b.?
