Jerusalem Talmud Shabbat
“And make an eruv, and store away hot food29Hot food to be kept warm for the Sabbath noon meal in insulating material as explained in Chapter 4..” Rebbi Ḥiyya bar Ashi said, this is about eruv of courtyards24The symbolic sharing of space, a courtyard or a dead-end street, by several families turning the space into their private domain with regard to the laws of the Sabbath; details are the subject of Tractate Eruvin. Sadducees considered pharisaic eruvim as Sabbath desecrations.. But eruvim of domains are a matter of biblical law239Since adjacent courtyards and dead-end streets are not thoroughfares, there is no biblical prohibition involved in declaring common ground as common private domain. The Sabbath domain belonging to a town is a rectangle oriented North-South and East-West containing the entire town and another 2000 cubits outside town in each of the cardinal directions, inspired by the description of Levitic cities in Num. 35:1–8. An Eruv Teḥumin is a personal action in which a person renounces his right to go outside town in one direction and in compensation may go 4000 cubits in the other direction. If another town would be reached in this space, that town also becomes part of his Sabbath domain. This action clearly involves public domain by biblical standards (even though the restriction to 2000 cubits may be purely rabbinical) and therefore must be completed before sundown..
