Quien entra en un pueblo pronuncia dos oraciones, una al entrar y otra al salir. Ben Azzai dice: Cuatro, dos al entrar y dos al salir. [Cuando está a punto de entrar, dice: "... que me conduces a este pueblo en paz". Una vez que ha entrado, dice: "Te doy gracias por haberme llevado a este pueblo en paz".—dos al entrar. Cuando está a punto de irse, dice: "... que me sacas de esta ciudad en paz". Una vez que se ha ido, dice: "Te doy gracias por haberme sacado de esta ciudad en paz". Y él da las gracias por el pasado y clama por el futuro. [¿Por qué todo esto? Porque uno debe dar gracias a su Creador por el bien que ha experimentado y debe orar por el bien en el futuro.]
Mishnah Avodah Zarah
If [a Jew] left his wine in a wagon or on a ship while he went along a short cut, entered a town and bathed, it is permitted. But if [the Jew] informed him that he was going away [and he was absent a length of time] sufficient for the other to bore a hole [in a jar], stop it up and [the sealing clay] to become dry, [the wine is prohibited]. Rabban Shimon ben Gamaliel says: [a length of time] sufficient for him to open a cask, put a new stopper on and [the new stopper] to become dry. If [a Jew] left a non-Jew in his shop, although he kept going in and out, [the wine there] is permitted. But if [the Jew] informed him that he was going away [and he was absent a length of time] sufficient for the other to bore a hole [in a jar], stop it up and [the sealing clay] to become dry, [the wine is prohibited]. Rabban Shimon ben Gamaliel says: [a length of time] sufficient for him to open a cask, put a new stopper on and [the new stopper] to become dry.
