The conquest of the land described in the book of Yehoshua took seven years (Arakhin 13a).1 It is only at the end of the conquest that Yehoshua dismisses the "shock troops". We know from Yehoshua 1...
On a fast day during Shacharit (the morning prayer), individuals do not say עננו / Aneinu (a special fast-day prayer), in case they don't complete the fast, and instead say it during Mincha (the af...
Asking for a friend: If I learn with a Chavrusa and we both finish a Masechta together, assuming that we wait until different days to make the Siyum (whether permitted or not), if we each attend th...
In Gen 47:22, during the years of famine, Joseph takes land from everyone except the Egyptian priests. This is in direct contrast to the Jewish priests who will not own land in the Land of Israel....
A post elsewhere cites Igrot Moshe (Yoreh De'ah 2:56) as saying that listening to (hearing?) Christian music is forbidden (asur). A comment there elaborates: He states that the restriction is r...
One of the songs commonly sung on Friday night, which begins Kol Mekadesh Shevi'i, follows an alphabetic acrostic. After the introductory stanza, each stanza contains four phrases: the first three ...
In various places on this site, including the FAQ, we have the following disclaimer: Like Wikipedia, this site makes no guarantee of validity, and does not offer professional (particularly rabbini...
On Tish'ah b'Av, it's a universal (I think) tradition to read megillat Eicha at night (and some also read during the day); see Shulchan Aruch 559:2. Generally, this is read in a communal setting, b...
In his commentary on Beresheet 36:31, Ibn Ezra writes: "ואלה המלכים. יש אומרים כי בדרך נבואה נכתבה זאת הפרשה. ויצחקי אמר בספרו כי בימי יהושפט נכתבה זאת הפרשה. ופי' הדורות כרצונו הכי קרא שמו יצחק כ...
In ancient times, the Roman pagan holiday of Saturnalia included a practice of baking some type of cake with a fava bean hidden inside, with a prize for whoever got the piece containing the bean. I...
This is a hypothetical question; it doesn't apply to anyone I know, but I heard an anecdote and it led me to wonder. Suppose someone discovers that her maternal grandmother was in fact Jewish, but...
The theme of the "Adama mei-arer" Hoshana-prayer that we say on Hoshana Rabba appears to be asking God to protect our agriculture. With one possible exception, every element appears to be about the...
Normally in my experience, a baby girl is named in the presence of a minyan, generally at a Torah reading. If her parents are not expecting to be with a minyan for the foreseeable future, should th...
Suppose someone started reading a haftara for a different week, or according to a different custom for the same week, or a piece of navi that's not a haftara at all. What should the community do? ...
In Mishnah Ketubot 1:1, it says: בְּתוּלָה נִשֵּׂאת לַיּוֹם הָרְבִיעִי, וְאַלְמָנָה לַיּוֹם הַחֲמִישִׁי. A virgin is married on the fourth day [of the week] and a widow on the fifth day Why don't...
An accidental killer flees to one of the cities of refuge for an indeterminate time (until the death of the kohein gadol, or even longer if the timing is unfortunate). The cities of refuge are cit...
Last night, as part of his weekly livestream COVID update, Rabbi Dr. Glatt quoted Rav Mordechai Willig that one should put a mask over the wide end of the Shofar while blowing to prevent spreading ...
At the end of Korbanos during davening there is a Baraisa that starts with רַבִּי יִשְׁמָעֵאל אוֹמֵר. It tells us of different methods of derivation that can be used throughout Tanach. Does anyone ...
I understand that one should take challah when baking bread made with at least 10 cups of flour. (That article says 14 for saying the b'racha but down to 10 for taking at all.) How does this requ...
In exactly three contexts, the Mishnah notes that there was an amah square marble slab with a ring, using exactly the same language each time. The first is in Sotah 2:2, regarding the Sotah procedu...
Bechorot 8a discusses a species called dolfinim, which, in Rashi's understanding, are merpeople and can bear viable offspring with humans. Let's suppose that merpeople actually exist as Rashi descr...

In several locations (example: Yoma 75a.14 ), Chazal mention that Bnei Yisroel had slaves even while they were in the midbar. Where did they get them from? Did they take them from Egypt? Did they t...
I'm somewhat competent in praying alone on weekdays and Shabbat, with the current pandemic providing a forcing function. I prefer to be part of a community and be able to rely on the sh'liach tzib...
My understanding is that the repetition of the prayer popularly referred to as the Shmoneh Esrei was instituted to assist people who were illiterate and could not say the prayer themselves. Since t...
In Bereishis 22, the story of the עקידת יצחק (binding of Isaac) takes place. When Avraham sets up the altar in Bereishis 22:9, the Pasuk says: וַיָּבֹ֗אוּ אֶֽל־הַמָּקוֹם֮ אֲשֶׁ֣ר אָֽמַר־ל֣וֹ הָאֱל...
Chaye Adam 138:5 writes: וראוי לכל אדם לטבול במקוה או בנהר ולא יקדים לטבול עד שעה קודם חצות היום In my own translation: It's seemly for every man to immerse in a ritualarium or a river [on the d...
Kind of a weird question. Does anyone have any idea what happened to the fruit brought by the spies from Israel to the desert? Was it eaten by specific people? Buried? Left behind?
Mishnayot Tamid 6:3 says that the kohen who wins the right to offer the daily incense brings a buddy with him to hold one of the vessels and help him retrieve any dropped incense: מִי שֶׁזָּכָה בַ...
If there is someone who does not yet own a Tallis (prayer shawl), and he is davening for the amud (so he wears a shul tallis), when he gets to the places in davening where you are supposed to kiss ...
Does a woman fulfill the obligation to hear the shofar during Elul if she blows it for herself, or is this one of the mitzvot where a man (must? should?) perform the action on behalf of others? Fo...
Everywhere that the term חנם appears, as far as I can tell, it always means "without personal benefit": a שומר חנם (Bava Metzia 7:8) watches an object without receiving anything in return; a Jewish...
There are many medicines which are permitted to be used on Shabbos in various situations. However, some of them have letters written or engraved on them. Is it permitted to take these pills on Shab...
Last week I took a class on priorities in triage -- one ventilator, two people who will die without it, who gets it? We reviewed sources in talmud and later commentaries, some of which I remember ...
In 2004, a group of rabbis in Israel attempted to begin the process of re-establishing the Sanhedrin using the Rambam's method of universal consensus to re-establish the line of semikha. Rabbi Mosh...
Avodah Zarah 6a.16-6b.1: והתניא: אמר רבי נתן, ״מנין שלא יושיט אדם כוס של יין לנזיר ואבר מן החי לבני נח? ת"ל (ויקרא יט, יד) ולפני עור לא תתן מכשול.״ It was taught in a Braisa: R' Nassan said, "Fro...
If semen was extracted from a dead man, and then used to impregnate a woman, is the offspring a legal son (let's limit it to male) of the dead man? Or, more simply put, is a child born of ones seme...
The Gemara (Berachot 38a) cites a dispute whether the blessing on bread is המוציא or מוציא. The issue is that the blessing must reflect the past tense; while everyone agrees that מוציא is past tens...
During the plague of darkness, the Jews went around to scout out what the Egyptians had in their houses and then they "asked" for things before they left and the Egyptians gave them lots. No doubt...
There are candles that are made from beef tallow (https://www.theprairiehomestead.com/2014/01/tallow-emergency-candles.html). If one were to burn one, residue and soot from incomplete combustion co...
Occasionally, I have to act as gabbai for a small minyan, where other members of my family also daven. When calling up my father for an aliyah, I use the formulation "יעמוד, אבי מורי הרב..." (Rise,...
After Yosef gave the brothers provisions, he kept Shimon (Bereisheet 42:24) there to guarantee that the brothers would return with Binyomin. They went home and didn't come back until they ran out o...
Generally speaking, whenever the Torah tells us "do not do X," the context is "do not do a specific action" (don't eat non-Kosher, don't do work on Shabbos, etc.). In a select few prohibitions, how...
The Nephilim are named only in two verses in the Bible, in Genesis 6:4 and Numbers 13:33. Numbers 13:33 says that the Anakim come from the Nephilim, but different translations render this in a vari...
I bought a package of frozen salmon filet pieces in Israel; they'd been imported from Poland. The package reads, in part: מטעמי הכשרות חובה לשטוף את העור או להסירו לפני השימוש. In my own tra...
In Bereishit 2:19 God brings all the animals to Adam to see what he will name them. This has long puzzled me, because: God created them and already knows their functions (He doesn't need Adam to ...
If one had placed a bouquet of flowers in a vase prior to Shabbat, is it considered muktzah? In what scenario would it be permissible to move it on Shabbat?
Once upon a time, I was on a trip up in north Georgia and stumbled across this gem: a security service branding itself as "Adonai Security, LLC." The tagline proceeds to make a pun in the same vei...
Suppose Reuven is ordained as a Rabbi (receives semicha). His teacher, Rabbi Yaakov, decides that he is learned enough and of the right character to serve as a Rabbinic authority and proclaims that...
Yoma 87a and Rambam Hilchot Teshuvah 2 both describe requirements for doing teshuva and gaining forgiveness. According to them, the one doing teshuva must first make restitution and then, in front...
