In this panel discussion given at the February Learning Seminar 2024, Hadar’s rashei yeshiva, R. Ethan Tucker and R. Aviva Richman, reflect on their approach to Jewish law and how our quest for God can be lived through the details of our halakhic lives.By Hadar Institute

Why has President Franklin Delano Roosevelt's dark side been hidden? Scholars consistently rank FDR as one of America's greatest presidents. The 2024 Presidential Greatness Project Expert Survey ranked him number two, below Lincoln, and respondents to the Siena College Research Institute studies have ranked him number one in six out of seven survey…

Is war with Iran coming? Last Saturday, Iran launched hundreds of armed drones and missiles to attack Israel in retaliation for an airstrike on an Iranian consulate in Syria that killed seven members of the Islamic Revolutionary Guard, including a general. Israel and the U.S. report that they intercepted most of the drones, and the sole known casua…

In celebration of 100 episodes of Responsa Radio, we're re-releasing our favorites with an update from Rav Eitan and Rav Avi at the end of the episode. Our producer, Jeremy Tabick's favorite is episode #7: The laws of eruv—constructing a sometimes questionable boundary around a neighborhood to allow carrying objects on shabbat—often seem obscure, b…

We Jews, who have been perennial outcasts, ought to read the Torah’s account of the leper with particular care.“Leper,” we should note from the outset, is not really an accurate rendering of the Hebrew, מצורע (metzora). The biblical affliction of tza’arat is clearly different from what we today call “leprosy,” most obviously so because it can only …

Ever wondered why we have to drink four cups of wine at our Seders? This class explores the history and the symbolism of this idea and how it transforms from something more functional to the framing around the entirety of Seder night. Fittingly, there are at least four different ways to think about these cups! Recorded on 4/10/24. Source sheet: htt…

At least 40 U.S. colleges still require a COVID vaccine, according to nocollegemandates.com, an initiative that tracks and opposes the mandates. Martin Kulldorff, a professor of medicine and biostatistician who lost his job at Harvard for refusing the vaccine even though he'd already survived a COVID infection, says such mandates are "unscientific"…

In celebration of 100 episodes of Responsa Radio, we're re-releasing our favorites with an update from Rav Eitan and Rav Avi at the end of the episode. Our sound engineer, David Khabinsky's favorite is episode #78: A few months ago, one of the largest kosher certification agencies announced that it would not certify "Impossible Pork," despite the f…

From the very beginning, the Torah imbues certain numbers with great significance. The first chapter of Genesis carefully divides Creation into seven days. Seven then becomes the most significant number in nearly all Jewish time rituals—not just Shabbat, but Pesah, Shavuot, Sukkot, as well as the seventh month, the seventh year, the seven cycles of…

There's a catchy song that tells us what we're supposed to do during the Seder and when (Kaddeish Urhatz). But when you dig a little deeper, the song is a little simplistic for the actual Seder structure. How can the giant Maggid section be covered by a single word? And why is Hallel actually split into two? Rav Elie discusses the overall structure…

"I discovered something remarkably similar to an alien co-intelligence," wrote Ethan Mollick in his new book Co-Intelligence: Living and Working with AI, describing the "sleepless nights" he experienced upon first encountering ChatGPT 3.5 in November 2022. Mollick, a professor at the Wharton School of the University of Pennsylvania and author of th…

I'm planning on going to the total solar eclipse that will be visible in North America on April 8th. is there a blessing or some other liturgy that I should say as I see it?By Hadar Institute

Throughout our history, one of the central institutions of a Jewish community has been the mikveh. Immersion in this ritual bath was required in Temple times in order to purify oneself after coming into contact with various types of tumah (ritual impurity). Since then, the practical need for a mikveh has been relegated primarily to the laws of sex …

Immigration ranks as the second-most important issue among registered U.S. voters and the top issue for Republican voters, according to a Marist Poll/PBS NewsHour/NPR poll released last month. Perhaps that's because of the 3.2 million border encounters documented by Border Patrol in 2023—a new record high that's so far being outpaced this year. Tex…

I was trying to help someone on the street get some food. They asked for a sandwich, so I went into a nearby shop—and suddenly panicked because I realized it was Passover! What was I supposed to do in this case? What are the parameters of buying and touching hameitz for non-Jews during the holiday?By Hadar Institute

For the most part, Parashat Tzav repeats much of what we learned last week in Parashat Vayikra. Again, the Torah details the choreography of the sacrificial system—only this time from the perspective of the priest. All of the offerings from last week show up again. But there is at least one thing that is unique to Tzav: a shalshelet.…

To what extent is Jewish law “fake” or “real”? Is halakhah a game where you can say whatever you want, or does a ruling, once issued, create a new reality? What are the underlying principles of kashrut and Jewish food laws? Recorded live at Hadar's Manger Winter Learning Seminar in January 2024. Source sheet available here: https://mechonhadar.s3.a…

Are American cities crime-ridden hellscapes right now? Have cities rebounded from pandemic-era homicide spikes? Why do subway shootings in New York and carjackings in D.C. keep making the news? "I think a lot of this has to be disaggregated: There is a public order problem, and there is a violent crime problem, and they're not necessarily the same …

My family are coming in from 1000s of miles away for the eclipse on April 8th, but they won't be around for Pesah on April 22nd. I want to do a mock or model Seder with them, but I know some things are only supposed to be done on actual Seder night. What should I include or exclude? How can I make the mock Seder feel substantive, but at the same ti…

The laws of Leviticus appear to be entirely separate from the narrative and themes of the Torah so far. Exodus, by contrast, picks up directly from the narrative of Genesis, and—as we have seen—even the case laws in Exodus sometimes make subtle references to earlier stories. But when we enter Leviticus, we feel ourselves to be in another kind of bo…

As someone who longs to feel God’s presence in my life in a clear and direct manner, I have always been struck by the fact that God is noticeably absent from Megillat Esther. In a story that is about the near demise and heroic salvation of the Jewish people, it is not God’s hand that is featured in this story as the saving force, but rather the hum…

Writer and podcast host Coleman Hughes published a column in The Free Press in January entitled, "What Really Happened to George Floyd?" in which he analyzes a documentary called The Fall of Minneapolis, which has racked up more than 6 million views on YouTube and Rumble. The documentary makes the case that former Minneapolis police officer Derek C…

There is something hidden in the mishkan. A story of creation. Nehama Leibowitz, the great 20th century compiler of Torah commentary, calls our attention to a group of modern scholars who sensitized us to the use of repetition as a rhetorical device in the description of the building of the mishkan. She cites a list of the greats: Buber, Rosenzweig…

I'm organizing my community's reading of Megillat Esther. Can I include English explanations or kids' plays between the chapters? What is at stake in breaking up the reading?By Hadar Institute

From one perspective, pregnancy is a miracle. But from another, pregnancy is a nightmare. In her essay that won the Ateret Zvi Prize in Hiddushei Torah, Rabbanit Leah Sarna argues that the Jewish tradition makes space for both of these stories about pregnancy. This presentation and conversation with Rabbi Tali Adler is from February 2024.…

Is there meaning in a measurement? Two great masters of midrashically-styled Torah commentary—both writing in 14th century Spain—will offer two very different interpretations of a particular form of measurement that appears frequently in this week’s Torah reading: the half.By Hadar Institute

Shabbat is described in the Talmud as a "good gift." But aren’t all gifts supposedly good? What makes Shabbat a gift that is uniquely positive in contrast to other gifts which do not receive this stamp of goodness? The Ohev Yisrael explores.

Bryan Johnson made his fortune when he sold his company Braintree to PayPal for $800 million, netting about $300 million for himself. He spends about $2 million a year creating a system to reverse his "biological age." He's 46 years old, chronologically, but claims he's de-aged himself following a program he's branded "the Blueprint protocol." "I w…

The person recovering from the biblical disease tzara'at has to bring, in addition to their offering, a piece of cedar wood and a piece of hyssop. The Ohev Yisrael tells us that these items are symbolic for the two character traits we need in order to do true teshuvah: pride and humility.

And if I can't do that, can I use a French press on Shabbat to g…

Parashat Ki Tissa makes repeated reference to God’s “face” when describing Moshe’s communication with God. But what exactly did Moshe see when he looked into the face of God? A comparison to Moshe’s own use of parallel imagery later in the Torah gives us a fuller sense of the visual experience of revelation.…

According to the Ohev Yisrael, the Israelites preferred to live under physical oppression in Egypt than to live in a state of spiritual indebtedness to God. How could this be?
