Da’as Rachamim Tif’eres

The Holy Refrain

The Eilu vaEilu Paradox

Teach Him Like the Laws of Pesach
חָכָם מָה הוּא אוֹמֵר? מַה הָעֵדוֹת וְהַחֻקִּים וְהַמִשְׁפָּטִים אֲשֶׁר צִוָּה ה׳ אֱ-לֹקינוּ אֶתְכֶם? וְאַף אַתָּה אֱמָר לוֹ כְּהִלְכוֹת הַפֶּסַח: אֵין מַפְטִירִין אַחַר הַפֶּסַח אֲפִיקוֹמָן. The wise [son], what does he say? “What are the...

Interpretations of Probability
At “Casting Lots” I tried to use the relationship between the field of statistics and Divine Providence as a means of looking at the verse “Hipil pur hu hagoral — he cast a pur,...
Casting Lots

Midgets on the Shoulders of Giants
Someone recently (when I first wrote an earlier version of this post, Feb 2007) asked me about nisqatnu hadoros, the decline over time from one generation to the next. How is this possible, given...

Shaarei Yosher, sec. 6: Refinement – Conclusion

Who fed the Egyptians?
During the second 3 days of choshekh in which the darkness was tangible and the Mitzriim could not move, how did they eat? After all, an oath not to eat for 3 days is...
Shaarei Yosher, sec. 6: Refinement – Part 2
One can use this to explain the whole notion of breaking the [first] Tablets, for which I have not found an explanation. At first glance, understanding seems closed off. Is it possible that Moses...
Precondition for a Fast
דלמא: ר’ בא בר זבדא, ורבי תנחום בר עילאי, ור’ יאשיה נפקוי לתעניתא. דרש ר’ בא בר זבדא (איכה ג:מא) “נִשָּׂא לְבָבֵנוּ אֶל כַּפָּיִם, [אֶל אֵ-ל בַּשָּׁמָיִם.].” “נשא לבבנו אל כפים” — ואיפשר כן”...

A Physics Metaphor for Coming to Terms with Theodicy
As I’ve mentioned in the past, Aristotle believed that motion was caused by an intellect imparting impetus to an object, which then moved until the impetus ran out. Newton replaced this model of physics...
Shaarei Yosher, sec. 5: Sharing – Part 2
With this idea one can understand how charity has the effect of enriching the one who performs it, as the sages say on the verse “‘aseir ta’aseir – you shall surely tithe’ – tithe,...
Malki-Tzedeq and Birkhas Avos
Compare these two snippets. I added color to highlight my point. First, Bereishis 14:19-20. A massive regional war just completed, and Avraham joins the kings he fought with. Malki-Tzedeq the king of Shaleim (the...
Shaarei Yosher, sec. 5: Sharing – part 1
