Jerusalem Talmud Eruvin
If he forbade himself a loaf by a vow it may be used as eruv, if he dedicated it it may not be used as eruv. If he forbade himself a loaf by a vow it may be used as eruv, since another person may eat it. If he dedicated it it may not be used as eruv, since neither he nor another person may eat it66Babli 30a.. Rebbi Aḥa asked, may not a person ask about his dedication67Since a dedication to the Temple is a vow, a dedication may be removed by rabbinic authority like any other vow. Then the dedicated item reverts to profane status and therefore always was potential food. Naturally the dedicated object should be redeemed and returned to profane status but this is not possible on the Sabbath and therefore not an option to validate an eruv on the Sabbath. The Babli notes that the disregard of possible removal of dedication is a separate rabbinic decree.? Rebbi Aḥa said that Rebbi Miasha asked: There Rebbi Simeon68This must refer to R. Simeon ben Laqish. said that Ḥiyya the son of Rav said, if one used idolatry69Wood from an ashera or an idol, forbidden for all usufruct. to make a lath it permits the alley, and here you are saying so? Rebbi Eleazar said, there in any case the alley was closed; here what do you have70Since the lath has no required minimal depth it is a sign, not a material presence. The material could not be used for a beam which has to be three-dimensional material.?
