The Blue Does Not Hold Up the White
התכלת אינה מעכבת את הלבן והלבן אינו מעכב את התכלת תפילה של יד אינה מעכבת של ראש ושל ראש אינה מעכבת של יד הסולת והשמן אינן מעכבין את היין ולא היין מעכבן המתנות של...

Dip the Apple in the Honey
Here are three thoughts related to the siman, the mnemonic practice, of eating an apple dipped in honey. (Aside from the ear-worm you or your kid learned in preschool that starts with the words...
Simanei Milsa
I was asked the following question, and the author thought enough people want to know the answer that it pays to share it here: Q: “Siman“, as on Rosh Hashanah night, is translated as...
Phenomenalism – Baruch sheKivanti!
The central thesis of this “Phenomenalism” category of this blog was built on two parts. The first is Rabbi Aqiva Eiger’s (RAE) explanation (shu”t, mahadura qama #136) that the ways in which uncertainty in...
Rejoicing of the Water-Drawing House
כָּל מִי שֶׁלֹּא רָאָה שִׂמְחַת בֵּית הַשּׁוֹאֵבָה – לֹא רָאָה שִׂמְחָה מִיָּמָיו! Whomever didn’t see Simchas Beis haShoeivah did not see simchah in all his days! –Mishnah Sukkah 5:1 The talmud on this mishnah...
Anavah and Anvanus
The story of Qamtza and Bar Qamtza is very well known. It is introduced by Rabbi Yochanan, who asks, “’What is the meaning of the verse in Mishlei which reads, ‘Fortunate is the one...
The Interpersonal Aspect of Parah Adumah
The most fundamental difference between the kind of reasoning one finds in the Bavli with that one finds in the Yerushalmi is “vertical” vs. “horizontal”. The Bavli will drill down to get the full...
Sanctuary of the King, the Royal City
Rav Shelomo al-Qabetz actually addresses much of Lekha Dodi to Jerusalem: “מִקְדַּשׁ מֶלֶךְ עִיר מְלוּכָה — Sanctuary of the King, the Royal City.” “הִתְנַעֲרִי מֵעָפָר קוּמִי \ לִבְשִׁי בִּגְדֵי תִפְאַרְתֵּךְ עַמִּי — Arise, get...
This Month Shall Be For you
In his first comment, Rashi opens his study of Chumash by repeating a medrash that asks why the Torah start with creation rather than with the first commandment to the Jewish People: הַחֹ֧דֶשׁ הַזֶּ֛ה...
Who knows 4?
Someone named Ray asked on Mi Yodea (in part), “What is the special fundamental significance of the number four that God’s primary Name has four letters”? I liked how my answer came out, so...
A Thought About Maoz Tzur
(Updated again for 2009, 2013 and now in 2016.) One line in Ma’oz Tzur I particularly love. The 5th verse of Ma’oz Tzur describes the Chanukah story. One phrase in this verse is “ufortzu...
From Your Homeland
Most young Yeshiva children come home sometime around Shavuos with the story of how Hashem offered the Torah to all the nations of the world, but only the Jews accepted it. The medrash, as...
Why didn’t we catch up?
Last Pesach ended in Israel on Friday, and in the rest of the world on Shabbos. Which means that in Israel, Acharei Mos was read that week, while we in chutz la’aretz (outside of...
Mesilas Yesharim and the Haggadah
Rav Moshe Chaim Luzzatto opens Mesilas Yesharim with this questionable claim: הקדמה – אמר המחבר: החיבור הזה לא חברתיו ללמד לבני האדם את אשר לא ידעו, אלא להזכירם את הידוע להם כבר ומפורסם אצלם...
Dandelion Whine
The gemara says that the preferred vegetable for maror is chasah — lettuce. The problem is that the lettuces sold today aren’t mar, bitter. One could try to find wild lettuce. The lettuce that was native to...
Sweet Charoses
(Embellished with thoughts from my daughter Noa’s recent bas mitzvah speech. Yay, Noa!) If you think about it, charoses is quite strange. On the one hand, as we learn in preschool and the Rambam writes,...
You too left Mitzrayim
The Mishnah (Pesachim 10:5, TB 115a-b), in a section quoted by the Hagadah, states: רבן גמליאל היה אומר, כל שלא אמר שלשה דברים אלו בפסח, לא יצא ידי חובתו. ואלו הן: פסח, מצה, ומרור…. בכל דור...
Chalav Yisrael
Colloquially, discussions of the permissibility of drinking USFDA milk tend to start with citing the Igeros Moshe, as though the norm of drinking it originated with Rav Moshe’s (RMF) responsa on the subject. But...
Purim in the World of Affection
There are four mitzvos one must fulfill on Purim: reading the megillah, matanos le’evyonim (gifts to poor people), mishloach manos (“shalachmones”), and the Purim se’udah. The first, reading the megillah, relates directly to the...
The True Hero of Chanukah
No, the title of this post doesn’t refer to HQBH, although clearly it could. (Or can it: Can we define “heroism” with respect to One for Whom there are no risks to take?) Nor...
Sefeiq Sefeiqa
Back in 2007, I posted 7 answers to the question of why we treat Torah law and rabbinic law differently. In particular, we are lenient when in doubt about a rabbinic law (safeiq derabbanan...
Marriage and Gender
While I’m on the topic of gender roles, I might as well put in my two bits about Obergefell v. Hodges. As others noted, it’s the first time that holding on to classical Jewish...
Gender Roles
Rather than assuming the level of duties the Torah imposes on men is the baseline, and asking why women are exempt, I want to flip the question around and ask why men are obligated....
Textualism and the Mishnah Berurah
I Dr Haym Solovetichik, in his famous paper “Rupture and Reconstruction“, describes a difference between the the Mishnah Berurah and the Arukh haShulchan as follows: This dual tradition of the intellectual and the mimetic, law as...
Halakhah and Virtue Ethics
In 1967 Phillippa Foote raised a thought experiment philosophers call the Runaway Trolly Problem. Here is how wikipedia describes it: There is a runaway trolley barreling down the railway tracks. Ahead, on the tracks,...
Talmudic Sources for Avoiding Qitniyos
Here are two possibilities for the source of the minhag. The Yerushalmi makes the same statement that we have in the Bavli, that dough made from rice and water undergo a sirchon, not chameitz. Then it continues...
The Great Seal of the United State of America
Resolved, That Dr. Franklin, Mr. J. Adams and Mr. Jefferson, be a committee, to bring in a device for a seal for the United States of America. – Journals of Continental Congress, July 4th,...
Marbim beSimchah
Esther’s life was overall a very tragic one. The story ends, and we’re told about Mordechai’s rise to political power and the taxes and all. Meanwhile, she is still married to a non-Jewish drunkard...
A Lion of Fire
“And they cried out in a great voice to Hashem their G-d” ((Nechemiah 9:4. The gemara’s quote is corrected here to match verse. The standard text reads “ויצעקו אל ה’ אלקים בקול גדול”.)) –...
The Time of Our Joy
Why is Sukkos called in our tefillos “zeman simchaseinu – the time of our joy“, or the Torah tell us at this holiday in particular “vehayisa akh sameich – you should only be happy”...
A Mishpat for the G-d of Yaaqov
תִּקְעוּ בַחֹדֶשׁ שׁוֹפָר, בַּכֵּסֶה לְיוֹם חַגֵּנוּ. כִּי חֹק לְיִשְׂרָאֵל הוּא, מִשְׁפָּט לֵאלֹקֵי יַעֲקֹב. Blow the shofar at the new moon, at the fullness for our holiday. For it is a choq [a trans-rational statute]...
Baal Nefesh Yachmir
Continuing on the prior post… A recurring topic on Avodah is the Mishnah Berurah’s use of the concept of ba’al nefesh yachmir, that while the halakhah itself allows for some leniency, “one who masters...
Pesach, Matzah, Maror
AishDas’s motto is lifted from the motto of HaOlim, founded by Dr. Nathan Birnbaum which existed from the 1910s through the 1930s, ending with the decimation of European Jewry. “Da’as, Rachamim, Tif’eres” — Knowledge...
Why the Middle Matzah?
So, I was asked in the middle of the second seder: Why do we break the middle matzah for Yachatz? Is there some significance to it being the middle matzah? Here was my off-the-cuff answer,...
Units of Measure
Pesach-time it’s common for people to start discussing how much matzah and wine one is obligated to eat, so why should I be any different? What are we trying to compute? The definition of...
