What is Talmud Tweets?

What is Talmud Tweets? A short, personal take on a page of Talmud - every day!

For several years now, I have been following the tradition of "Daf Yomi" - reading a set page of Talmud daily. With the start of a new 7 1/2 year cycle, I thought I would share a taste of what the Talmud offers, with a bit of personal commentary included. The idea is not to give a scholarly explanation. Rather, it is for those new to Talmud to give a little taste - a tweet, as it were - of the richness of this text and dialogue it contains. The Talmud is a window into a style of thinking as well as the world as it changed over the centuries of its compilation.

These are not literal "tweets" - I don't limit myself to 140 characters. Rather, these are intended to be short, quick takes - focusing in on one part of a much richer discussion. Hopefully, I will pique your interest. As Hillel says: "Go and study it!" (Shabbat 31a)

Eruvin 10 – It’s a Matter of Perspective

The previous Talmud pages (2-9) have been spurred by only one sentence in the Mishnah:

[A CROSS-BEAM SPANNING] THE ENTRANCE [TO A BLIND ALLEY] AT A HEIGHT OF MORE THAN TWENTY CUBITS SHOULD BE LOWERED.

Uncommented on until now was the sentence which followed:

R. JUDAH RULED: THIS IS UNNECESSARY.

Although it has come up on previous pages, we have discussion now on width, not height, based on the conclusion of the Mishnah from page 2:

AND [ANY ENTRANCE] THAT IS WIDER THAN TEN CUBITS SHOULD BE REDUCED [IN WIDTH]

This “reduction” in the width of an entrance can occur with the use of side-posts. But it can get complicated when one courtyard or alley leads into another through a hole or breach. The side-posts might be flush from one perspective. And, although it is greatly argued, that matters:

it must be concluded [that a post that can be] seen from without but appears even from within cannot be regarded as a valid side-post. This is conclusive.

Similarly, a barrier might be erected in the middle of a 20 cubit wide entrance making two parallel “doorways.” Maybe it’s just a symbolic divider?

Levi learned: If [an entrance to] all alley was twenty cubits wide a reed may be inserted in the center of it and this is sufficient.

Ah, no:

He himself has learnt it and he himself said that the halachah is not in agreement with that teaching

Instead a strip of boarding is constructed 10 handbreadths high by 4 cubits long and placed in the middle of the entrance parallel to the length – effectively creating two alleys.

Illusion and perspective: these matter!
