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 36 – Quantum Flux

An eruv allows a person to travel up to 2000 cubits in any direction on Shabbat. But, according to the Mishnah, it can be retroactively set to allow double that in one direction. And the need can be flexible:

MISHNAH. A MAN MAY ATTACH A CONDITION TO HIS ERUV AND SAY, ‘IF FOREIGNERS CAME FROM THE EAST MY ERUV [SHALL BE THAT] OF THE WEST; [IF THEY CAME] FROM THE WEST MY ERUV [SHALL BE THAT] OF THE EAST;

That is, if I need to escape in one direction, the travel limits can be piled on into that direction.

IF THEY CAME FROM BOTH DIRECTIONS I WILL GO IN WHATEVER DIRECTION I DESIRE, AND IF THEY CAME FROM NEITHER DIRECTION I WILL BE LIKE THE PEOPLE OF MY TOWN’.

But not just running away – running to as well!

 [HE MAY LIKEWISE SAY,] ‘IF THE SAGE CAME FROM THE EAST LET MY ERUV [BE THE ONE] OF THE EAST; IF FROM THE WEST LET MY ERUV [BE THE ONE] OF THE WEST; [IF A SAGE] CAME FROM EITHER DIRECTION I WILL GO IN WHATEVER DIRECTION I DESIRE, AND IF NO ONE CAME FROM EITHER DIRECTION I WILL BE LIKE THE PEOPLE OF MY TOWN’(limited to 2000 cubits in one direction).

 R. JUDAH RULED: IF ONE OF THEM WAS HIS TEACHER HE MAY GO ONLY TO HIS TEACHER, BUT IF BOTH WERE HIS TEACHERS HE MAY GO IN WHATEVER DIRECTION HE PREFERS.

The rabbis say the “foreigners” one is running away form might be tax collectors. Or landlords. Run away!

What’s interesting is the retroactive element defining the shape of the travel limit. It is like a quantum field which operates in all possible states simultaneously, until it is observed and then collapses into one.

Run away!
