02. Tzurat Ha-petaĥ

We have learned (21:8-9) that according to most poskim, today’s streets are considered a karmelit. Thus, to permit carrying in the streets, it is sufficient to surround them with structures resembling doorways (tzurot ha-petaĥ), which form a kind of wall … Continue reading

07. An Eruv Where Shabbat Desecrators Live

The eruv, the two meals’ worth of food that all residents within the enclosed area own jointly, unites all the residents and renders the enclosed area a private domain, where carrying is permitted. However, all this is on condition that … Continue reading

08. An Eruv That Becomes Invalidated on Shabbat
