Jochanan, Gavriel and R. Noam Kaplan discuss the history of different wordings of the prayer texts, the the value of liturgical diversity, and the senselessness of the notion that there is an obligation to follow an ‘ancestral’ nusach. R. Noam also says a few words about his siddurim. Get full access to מקור מים חיים at mekormayimhayim.substack.com/subscribe | |||

| Why you've been reading the Hakdamah wrong: a discussion of the Lorberbaum interview | 03 Feb 2026 | 01:02:09 | |
Last episode, we interviewed prof. Yair Lorberbaum concerning major hiddushim he introduces in two recent articles of his on the Hakdamah (introduction) and Hilchot Mamrim in the Rambam’s Mishneh Torah. In this episode we summarise his arguments in English and discuss their significance and implications: * What parts of the Talmud Bavli did the Rambam really say are binding and what is the role of national acceptance? * How this limits the extent of the problem of the authority of the Babylonian courts * Why did the Rambam write the Hakdamah in this way?

| פרופ' יאיר לורברבוים: לקרוא את הרמב"ם נכון | 27 Jan 2026 | 01:13:14 | |
אנו משוחחים עם יאיר לורברבוים, פרופסור מן המניין בפקולטה למשפטים באוניברסיטת בר-אילן. נושא הדיון שלנו הוא שני מאמרים שפרסם לאחרונה ועניינו אותנו מאוד: * האומנם, לפי הרמב”ם, התלמוד הבבלי הוא ספר החוק (והאם) מפני שהסכימו עליו כל ישראל? * “פשט הדבר בכל ישראל”: הרמב”ם על אודות הסכמה על גזרות, מנהגות ותקנות במחקרו עוסק פרופ’ לורברבוים בתחום המשפט העברי, תורת המשפט, הפילוסופיה של ההלכה, ומחשבת ישראל. במוקד מחקריו עומדים התיאוריה המשפטית של ההלכה והקשר בין משפט עברי והלכה לבין פילוסופיה ותאולוגיה בתקופות השונות, במיוחד בתקופות חז”ל והראשונים. ראשי פרקים 0:57 הקטגוריות ההלכתיות של הרמב”ם 9:19 תפקיד ההסכמה לחקיקת חכמים וההבדל בין הסכמת רוב העם להסכמת כל העם 27:45 האם התלמוד הבבלי הוא ספר החוקים של ההלכה? 42:50 באיזה בית דין מדובר? מהי סמכות חלקי התלמוד שלא מהווים חקיקה? 52:10 האם ההקדמה תואמת את ההיסטוריה? 1:01:08 למה ההקדמה כה עמומה? למה טעו רבים כל כך בפירושה?

| Halacha and Kabbalah (iii) | 27 Nov 2025 | 00:44:31 | |
Issues discussed here include: The real factions in medieval Judaism (not just rationalist vs. mystical) How Kabbalah became legitimised (Ramban/Nachmanides had a lot to do with it) How the Zohar was a rebellion against Ramban’s elitist legacy The Spaniard that Gavriel couldn’t remember the name of was Yitzhak ben Moshe haLevi, also known as Profiat Duran, an interesting character in himself.

| What is the Tosefta? | 10 Oct 2025 | 00:56:23 | |
When was the Tosefta composed, and where did it come from? Did Rabbi Yohanan know the Tosefta? Did the Geonim? And, of course, why learn it?Not what I (Johanan) thought. Gavriel explains. Some things we reference in the podcast: * Article by ‘YU person’ whose name escaped us (Yaakov Elman) * The project proposed by Gavriel as a way to better texts of the Oral Torah (aka the ‘Mishna Project’) * More about the birkat kohanim example we discuss Get full access to מקור מים חיים at mekormayimhayim.substack.com/subscribe | |||
| Halacha and Kabbalah (ii) | 22 Jul 2025 | 00:35:53 | |
This episode was intended to deal with the doctrinal and practical influence of kabbalah up until its culmination in Sabbateanism, including major updates from the current state of the literature. Unfortunately, our new microphones ran out of battery half way through, so only the first part survives. We hope to cover the rest (which really deserves an episode of its own, anyway) in another episode soon. Issues discussed here include: * Evolving views on the authorship and composition of the Zohar * Explaining the mystery of how one man wrote the Zohar (he didn’t). * How the Zohar came to be considered authoritative among poskim * How hearsay influenced halachic practice Get full access to מקור מים חיים at mekormayimhayim.substack.com/subscribe | |||
| R. Noam Kaplan: laws the Gemara forgot to tell us | 07 Jul 2025 | 01:10:30 | |
We are joined by Rav Noam Kaplan, שליט”א for a wide-ranging conversation about halachot commonly asserted today which Hazal… seem to have forgotten to tell us about. Topics include eiruvim, the kashrut of steam from food, bitter herbs, and the necessity of maintaining two sets of cutlery.Rav Noam received his ordination from R. Zalman Nechemia Goldberg. He has served as rabbi of the Auckland Hebrew Congregation in New Zealand, is the author/compiler of סידור נועם השם alongside several other siddurim, and an early adopter of tekhelet. מקור מים חיים is a reader-supported publication.

Slifkin’s Evolution of the Olive * Revi’it Steadying the storm in the kiddush cup * Wine A link in case you were puzzled by Johanan’s little inside joke * Soft matzah We forgot to mention, but of course (with due care), you can make your own * Error correction: I (Gavriel) misattributed the citation of a phantom Tosefta regarding drinking the cups of wine without a break.

| Halacha and Kabbalah (i) | 16 Mar 2025 | 01:12:36 | |
In this episode, we start what will be IYH an extended discussion of the issue of kabbalistic influence on the development of halacha. Gavriel has been studying the history in some detail recently, and found that it re-radicalised him against kabbalah, whereas Johanan felt the discussion nuanced things somewhat. Chime in with your thoughts! Some of the topics we address: * The history of the reception of the Zohar * The effect of the expulsion from Spain * The conservative nature of pre-Tzfat kabbalah * The reinvention of Kabbalah in Tzfat * The role of the Beit Yosef * Misinterpretations of the Zohar in halachic works * The duality of kabbalah as an elite-mystical and popular movement Get full access to מקור מים חיים at mekormayimhayim.substack.com/subscribe | |||
