An Eruv<\/em> That Becomes Invalidated on Shabbat"},"content":{"rendered":"

Sometimes it becomes apparent during Shabbat that a wire from the eruv<\/em> has snapped in a certain place, thus invalidating the eruv<\/em>. Two questions then arise: 1) May the eruv<\/em> be fixed on Shabbat? 2) If it turns out that the eruv<\/em> cannot be fixed, do all the residents need to be informed that the eruv<\/em> is down so they know not to carry?<\/p>\n

Le-khat\u0125ila<\/em>, if a non-Jew is available, it is preferable that he fix the eruv<\/em>. Although asking a non-Jew to do melakha<\/em> for Jews on Shabbat is rabbinically prohibited, nevertheless, when there is a great need to save the masses from the prohibition of carrying on Shabbat, the Sages permitted asking a non-Jew to fix the eruv<\/em>, even if this will involve melakhot<\/em> that are prohibited by Torah law (MB 276:25; above 9:12).<\/p>\n

However, if no non-Jew is available, a Jew certainly may not violate Torah prohibitions in order to fix the eruv<\/em>. For example, if a pole has fallen over, a Jew may not stand it back up by jamming it into the ground. Similarly, if the wire has snapped, one may not tie it back together with a permanent knot, as tying this type of knot on Shabbat is forbidden by Torah law. However, the poskim <\/em>debate whether one may tie a bow knot (the type used to tie shoelaces), as tying this type of knot on Shabbat is permissible.<\/p>\n

Some argue that fixing the eruv<\/em> on Shabbat is absolutely forbidden. Even though it is permissible to tie a bow knot on Shabbat, nevertheless in this case tying it would permit carrying on Shabbat. This means that by tying it, one constructs a me\u0125itza ha-materet<\/em> (above, 15:4), which is forbidden on Shabbat. In other words, the Sages prohibited making a wall that serves to permit something that was previously halakhically forbidden. In this case, before one tied the knot it was prohibited to carry, while afterward it was permitted.<\/p>\n

Others maintain that although the Sages generally forbade constructing a me\u0125itza ha-materet<\/em>, nevertheless, in order to save the masses from sinning by carrying on Shabbat, one may create a me\u0125itza ha-materet<\/em> by tying a bow knot. This is the common custom (Responsa<\/em> Mahari Ashkenazi<\/em> \u00a713; Panim Me\u2019irot<\/em> 1:30; Sho\u2019el U-meshiv<\/em>, Mahadura Tinyana <\/em>1:89; SSK 17:34).<\/p>\n

If the eruv<\/em> cannot be fixed, this should not be announced publicly. This information is withheld out of concern that some people will carry anyway, desecrating Shabbat knowingly, and it is better that they transgress unknowingly rather than knowingly. The only people who should be informed are those who will definitely follow the halakha<\/em> and refrain from carrying.[7]<\/a><\/sup><\/p>\n

\n
\n
\n[7]<\/a>. This is the approach of Ma\u0125shavot Be-etza<\/em> \u00a716. In principle, whenever there is a chance that people will listen, even if it is more likely that they will not, we do not say that \u201cit is better that people transgress unknowingly rather than knowingly.\u201d As long as there is a chance that they will listen to reproof, we must reprove them (MB 608:3 based on Rosh). Accordingly, it would seem at first glance that the public must be informed that the eruv<\/em> is down, as there is a chance that many people will follow the halakha<\/em> and refrain from carrying. Nevertheless, R. Shlomo Zalman Auerbach explains (SSK ch. 17 n. 139) that carrying unknowingly in this case is considered even less severe than transgressing unknowingly in general; since people believe the eruv<\/em> is still valid, as far as they know they are carrying permissibly. Thus, one who carries in such a situation is viewed as transgressing a rabbinic prohibition obliviously (mitasek<\/em>). Therefore, it is better not to announce that the eruv<\/em> is down.\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
