Eruvin 40 - Friday September 18, 29 Elul

A different version of the story of Rav Sheshet and Rav Nachman in the Exilarch's house is told by Rav Ashi - the issue regards an animal brought from outside the techum and not two days of Yom Tov. The gemara discusses halachic issues regarding melacha done by a non-Jew for a Jew on Shabbat or chag. Can the Jew benefit? If so, when? Does it depend if it were done specifically for you or for a different Jew? What if it was done for non-Jews? Does one need to mention Rosh Chodesh in the Rosh Hashana davening? Does one say the shehechiyanu blessing on Rosh Hashana and Yom Kippur?
