Thought for the Day: No, You May Not Grape Jelly During the Nine Days; Yes, You Should be *VERY* Wary of Getting a P'sak Halacha from AI

The OU has a very nice program called Halach Yomi that consists of a daily (except legal holidays) email that covers a broad range of halachic topics. ( More about this program and to subscribe here. ) In a recent Halachi Yom, the topic of food made with even small amounts of meat or wine was discussed. My wife and I read and discuss them in the morning during breakfast. After reading/learning through the email, my wife asked, "So what about grape jelly?" Hmmm... good question. I never thought about it, nor had I seen it discussed. I decided to do some research. In the old days, I would have just Googled for any references to grape jelly, nine days, Tisha b'Av, etc. Then I would have perused the hits until I found something relevant/interesting. I like to do research before talking with the dayan so I don't waste his time. Now we have AI, so that saves me time also, right? Well... Let me walk you through my journey. I decided to start my research be looking for the br...

Thought for the Day: ספק דרבנן לקולא -- What Kind of Doubt/Uncertainty/Inconclusiveness Leads to a Leniency?

Everyone loves a good leniency. There is a famous dictum that applies to all areas of halacha: ספק דרבנן לקולא, ספק דאורייתא לחומרא/Where an irresolvable doubt is present: with regard to Rabbinic decrees, we rule leniently; with regard to Torah prohibition, we rule stringently. A famous example that comes up annually is respect to counting the Omer when one has definitely missed a day. On the one hand, it might be that the counting of each and every day is the fulfillment of a Torah requirement; therefore, we continue to count the rest of the days. On the other hand, it might not be a mitzvah at all once a day has been missed, in which case it would be innappropriate to make a bracha. Since (nearly) all brachos are mandated by Rabbinic decree, one does not make the bracha before counting the days of the Omer after the missed day. So far, so good. Boringly straightforward at this point in my learning. Imagine my surprise, then, when I learned (Yoreh Dea 92:7) that one can be lenient...

Thought for the Day: We Are All in This Together, Baruch HaShem

There is very little rhyme or reason for how a topic for a TftD gets chosen. Basically, I learn something, think, "Oh, cool!" and then write it up.... as soon as I have time, which has been quite limited recently. As a consequence, I have a growing backlog of "oh cool" thoughts that I am itching to publish. That being the case, I may as well choose one that goes together with the epoch in which we once again find ourselves—the Three Weeks—which began with the fast of שבעה עשר בתמוז and culminates with the commemoration of the destruction of the Temple, may it be rebuilt soon and in our lifetime, on תשעה באב. I was discussing a question on Chumash this last week, and of course we looked at the רש''י on that verse. After realizing that I had fully understood what רש''י was saying, I commented that someday I need to actually learn רש''י and not just read it every week. The expression "I saw an interesting רש''י this week" is ju...

Thought for the Day: How/Why "Great Monetary Loss" and "Pressing Circumstances" Is a Thing in Halacha

I am a physicist by predilection and training. I made a living programming computers for decades. I feel I can make the following statement as a domain expert in the area of reality: There is no physical law, nor is there any computer instruction that ends with "except in cases of great monetary loss or pressing circumstances." When I had cancer, not a single doctor—and I was very fortunate to have had two Jewish, Torah-observant doctors managing my case—said that I needed chemotherapy... unless that would cause me to incur a great monetary loss or if it was just too much pressure. (It was, in fact, both; in spades.) This has nothing to do with anything, but my grammar checker didn't like that last parenthetical statement. So I asked Gemini about it, and I got the following response: This statement is an idiomatic construction used to confirm that something possesses two distinct qualities or characteristics simultaneously, and to an extreme or significant degree. "I...

Thought for the Day: Gerim are Produced by Their Nation, Not Mined from Them

I am currently saying kaddish for my mother-in-law, a"h. I have also organized learning mishnayos as an elevation for her neshama. I feel honored to be able to do this; she was important in our lives, and the way she reared my wife prepared her to be able to grow into a fully Torah-observant bas yisrael. I also learn mishnayos for the yahrtzeit of my father, a"h, and my father-in-law, a"h. Again, it is a zchus for me, and I do not take that lightly. I do neither of those things for my mother. No complaints, just saying. For whatever reason (likely because I am in the middle of doing so much for our Jewish parents right now), though, I decided to ask R' Fuerst this year if I should  be doing any of those things for my own mother. I started with, "I haven't been saying kaddish for my mother on her yahrtzeit; should I be?" (My follow-up question would have been, "Jewish or Goyish calendar?") The dayan answered, "It's a free country....

Thought for the Day: Rearing תלמידי חכמים as a Segula for Shalom Bayis

I endeavor to make a siyum every year on my anniversary/birthday. Last year I made a siyum on Nedarim, leaving just Nazir and Sotah to complete Seder Nashim (of gemara). That  meant that I would be making a siyum on Seder Nashim for my 50th wedding anniversary. Cool, no? As it turns out, though, I have actually made progress in my learning skills and/or I have retired, so I have more time to learn in the mornings. In any case, I now learn two or three daf a week instead of one. That  means that I can be m'sayim Seder Nashim this year, בעזרת השם, on our 49th wedding anniversary. (I don't feel the coolness of making the siyum on year 50 would justify delaying; besides, I concocted a justification.) That  meant, though, that I had to find another date to sponsor kiddush at our Vasikin Minyan for the siyum. This is my morning seder at Brisk. I learn before davening in the winter and after davening in the summer, so I like to make the siyum there. Also, it is where my wif...

Thought for the Day: Kabalas Torah and the Bas Mitzvah Celebration of Bea Buder, a"h

Yes, I know very well that I have not written in quite some time. A discovery we made while cleaning out my mother-in-law's apartment seems a very fitting topic for my re-entry. After days and hours of sorting through boxes of documents and pictures, we were rewarded with two notable treasures: (1) a pair of diamond studs that had been presumed lost. (2) my mother-in-law's bas mitzvah speech. In truth, the value of the diamond studs pales in comparison to the speech find, but we had talked about those diamond studs for weeks (in fact, my mother-in-law, a"h, had also been bothered by their loss). The speech (and picture of her from that day!) solidified and deepened our appreciation for how much we owe to my mother-in-law, ברכה פייגא בת יעקב, ע''ה, A few years ago, I read a powerful משל/allegory in the Passover haggadah from R' Matisyahu Salomon. There was a bloke who wanted to know what it felt like to get the royal treatment. He hatched a plan to dupe a remote...
