Talmud for Eruvin 208:12

Rav Jeremiah in the name of Rav: They permitted planks for wells only for pilgrims¹⁹The three yearly pilgrimages to the Temple. This implies that after the destruction of the Temple all the rules of the present Chapter became obsolete. Babli 20b as accepted doctrine.. Rav Abin said, at the time of pilgrimage²⁰The suspension of the universal requirement that “what is standing must be more than what is breached” is authorized only temporarily for the needs of actual pilgrims.. Rebbi Jeremiah in the name of Rebbi Samuel bar Rav Isaac: Because of the pilgrims²¹But along the pilgrim’s route from Babylonia to Jerusalem the installations are permanent.. Rebbi Ezra said before Rebbi Mana, the Mishnah implies that one makes planks for wells in the present time²²Since the Mishnah is formulated in the present it must be valid in the present, after the destruction of the Temple and the end of pilgrimages.. But did we not state²³Mishnah 10:12., “one fills from the cistern of the diaspora with a wheel on the Sabbath, from the large cistern, etc.” Why “may one fill from the cold well²⁴While the cisterns mentioned in the Mishnah were on the Temple Mount, the well was somewhere on the pilgrims’ route. Using a mechanical contraption is rabinically forbidden on the holiday since one might be tempted to fix it in case it broke on the holiday. with a wheel on the holiday”? But at the time when Israel came from the diaspora and camped at this well, the prophets among them stipulated that that one could fill from the cold well with a wheel on the holiday²⁵Babli 104b. Tosephta 8:22.. They did not permit all cold wells, only this well at which they camped. As you are saying there, what was permitted was permitted, and here what was permitted was permitted. Rebbi Eudaimon from Haifa instructed in Haifa, Rebbi Jeremiah instructed in Ḥelef about planks for wells in the present time²⁶The Babylonian point of view is rejected..
