 We are continuing in siman 1, and left off discussing the modern equivalents for the shiurim given for the 2000 amos of the techum. We learned that there are three primary opinions as to how to calculate an amah. The opinion of Rav Avraham Chaim Naeh ztl is that an amah is rounded to 18 […]

 We are continuing in siman 1, discussing the ideas introduced by the Chayei Adam regarding techum. The third point we mentioned is that techum does not apply on a Torah level when traveling on a river. The fourth point was that there is a safeik whether techum applies 10 tefachim above ground, and that we

  We are continuing in siman 1. We will not learn this part of the siman inside, but will touch on the points introduced by the Chayei Adam and clarify them. The main idea behind learning this Klal is that some of the ideas introduced have relevance beyond the Klal itself, so we will go

  We are beginning Klal 4, which discusses the issue of a person boarding a boat when they will end up on the boat over Shabbos. Although the practical contemporary applications of these halachos are uncommon, since the rishonim give multiple explanations of these halachos, it has many practical applications.   In Maseches Shabbos, 19a,

  We have finished siman 26, and have been discussing the use of machinery on Shabbos. We left off discussing a case of a millstone and the placement of grain into the hopper (the feeder to the millstone) on Shabbos. Today, we will discuss the issur for a Jew to place grain into the hopper,

  Be’ezras Hashem, our 100th Shabbos shiur is coming up soon, and is available for sponsorship! Please contact shiurim@dvarhalacha.com for more information.  We are continuing in siman 26. The Chayei Adam is discussing a millstone, and wrote that even though there is no concern for maris ayin, there is a concern for zilusa d’Shabbos as

 Be’ezras Hashem, our 100th Shabbos shiur is coming up soon, and is available for sponsorship! Please contact shiurim@dvarhalacha.com for more information.   We are beginning siman 26. A person is allowed to set melacha in motion on Erev Shabbos with the melacha continuing into Shabbos, because there is no melacha being done on Shabbos itself.

  Be’ezras Hashem, our 100th Shabbos shiur is coming up soon, and is available for sponsorship! Please contact shiurim@dvarhalacha.com for more information. We are beginning siman 25. The Chayei Adam discusses a Jew who owns an animal through shutfus (jointly) with a non-Jew. The problem is that the Torah gives us a mitzvas asei of

We are beginning siman 23. The Chayei Adam continues to discuss shutfus, as he discussed in siman 21.  In a scenario where a business is buying and selling and generating a profit, there needs to be an arrangement from the beginning of the partnership in a way which gives the profits from Shabbos to a

 We are continuing in siman 22, discussing the issues involved in a non-Jew using a Jew’s item on Shabbos. We learned that even though it is muttar for the non-Jew to use a Jew’s item on Shabbos, the non-Jew cannot remove the item from the Jew’s home on Shabbos itself due to  chashad. We learned

 We are beginning siman 22. The Chayei Adam moves away from the amira l’achum issues we have been discussing to discuss the issue of a Jew’s item being used on Shabbos by a non-Jew. Eventually, we will come to a concern of maris ayin of amira l’achum, but before discussing maris ayin, the question is

 We are continuing in siman 21, discussing a shutfus (partnership) relationship between a Jew and non-Jew regarding work on Shabbos. We learned that they should stipulate before beginning the partnership that the non-Jew retains the profits from Shabbos, and the Jew retains the profits from a corresponding day during the week.  If they did not

We are beginning siman 21, where the Chayei Adam discusses another type of relationship between a Jew and non-Jew. Until now, we have discussed three types of relationships: Kablan, where the non-Jew is not paid per job and is not paid until he has finished the job. While he is working, he is considered working

 We have finished siman 12. We learned that even when the Jew does not receive direct benefit from the work performed by the non-Jew on Shabbos (because the non-Jew pays a fixed fee to the Jew and keeps all of the profits), there can still be an issue of maris ayin. In simanim 13. 14

  We are continuing in siman 12, discussing the seventh criterion for it to be permitted to make an arrangement with a non-Jew before Shabbos regarding melacha on Shabbos. This criterion is that the Jew cannot gain any economic benefit from the work which the non-Jew is doing on Shabbos.  Yesterday, we discussed the example

We are continuing in siman 11, discussing mail on Shabbos. We have discussed sending and receiving mail on Shabbos; today we will clarify a point regarding receiving mail.   We learned yesterday that if mail was sent to a Jewish recipient by someone else, the Jewish recipient may benefit from it. However, we must clarify that

  We are continuing in siman 11, discussing mail on Shabbos. We have discussed sending mail on Shabbos; today we will discuss receiving mail.     If the non-Jew knocks on the door and wishes to hand-deliver the mail, it is preferable to have the non-Jew put it down. The reason is due to the possibility

 We are continuing in siman 11, discussing mail on Shabbos. We have learned that a Jew cannot place a letter in the mail on Shabbos itself, but could place it in a public mailbox on Friday even if it will not be processed until Shabbos. The Jew cannot have the non-Jew take it from the

MWe are beginning in siman 11. We will not learn the entire siman inside. The Chayei Adam will discuss mailing items on Shabbos. The Chayei Adam writes that based on what we have learned, a person cannot put outgoing mail into the mail on Shabbos. Even though the mailman is a kablan, and there is
