SHABBOS 147 (10 Av) - Dedicated by Rabbi Dr. Eli Turkel of Ra'anana, Israel, in memory of his father, Reb Yisrael Shimon ben Shlomo ha'Levi Turkel. Isi Turkel, as he was known, loved Torah and worked to support it literally with his last ounce of strength. He passed away on 10 Av 5740.


1. One is forbidden to brush dust off of his clothing on Shabbos.
2. The Mishnah says that one may not bring his towels home on Shabbos lest he squeeze them.
3. Liquid medicines work well between Pesach and Shavuos.
4. Rebbi Elazar ben Arach forgot his learning after too much bathing in the Diyumsis River and drinking Frogyasa wine.
5. There is a dispute about whether one is allowed to cause himself to vomit with his hand on Shabbos.


1. This is considered whitening (which is one of the Melachos).
2. This applies even if he used ten towels (meaning that there is not a lot of wetness in each one) to dry himself.
3. There was a salty river with healing properties called Diyumsis that existed only for 21 days of the year. The 21 days either started or ended with Shavuos.
4. The Gemara says that this same combination of bathing and drinking caused the exile of the Ten Tribes, as they stopped learning and became immersed in worldly pleasure instead. Rebbi Elazar ben Arach's friends prayed for him, and subsequently he was able to remember his learning.
5. Rebbi Yochanan: It is forbidden to take a medicine on Shabbos that induces vomiting, but it is permitted to do so by hand. Rebbi Nechemyah: One may not induce vomiting by any means, even on a weekday, since it may cause a loss of food (Bal Tashchis).
