Shabbat

Then in the case of a community['s] too, it is fit for giving a drink to a poor child?  Moreover, as to what was taught: 'Just as a shofar may be moved, so may a trumpet be moved': with whom does that agree? — Rather [reply thus]; there is no difficulty: one agrees with R. Judah, one with R. Simeon, and one with R. Nehemiah;  and what indeed is meant by 'shofar', a trumpet,  in accordance with R. Hisda. For R. Hisda said: The following three things reversed their designations after the destruction of the Temple: [i] trumpet [changed to] shofar, and shofar to trumpet. What is the practical bearing thereof? in respect of the shofar [blown] on New Year.  [ii] 'Arabah [willow] [changed to] zafzafah and zafzafah to 'Arabah. What is the practical bearing thereof? — In respect of the lulab  [iii] Pathora  [changed to] pathorta  and pathorta to Pathora. What is the practical bearing thereof? — In respect of buying and selling.  Abaye observed: We too can state: Hoblila [changed to] be kasse and be kasse to hoblila.  What is the practical bearing thereof? In respect of a needle which is found in the thickness of the beth hakosoth,  which if [found] on one side, it [the animal] is fit [for food]; if through both sides,  it [the animal] is terefah.  R. Ashi said, We too will state: Babylon [changed to] Borsif and Borsif to Babylon.
