Eiruvin 33a, b

Such a short daf!  I was prepared for a quicker than usual read.  But, as often happens when reading Talmud, I became flustered and lost.  I must have reread this daf four times.  

Today we learn about more about establishing an eiruv on a tree.  Depending on the height of the horizontal portion of the trunk, the width and the depth of the trunk, an eiruv may or may not be prohibited.  And we can't forget about timing - whether it is twilight or truly Shabbat makes a difference.  And if the eiruv is in a basket that is attached to the trunk, that will change things as well.  The width of the trunk now changes.  And whether or not the food can be emptied by tilting the basket influences rabbinical decision-making, too.  

The rabbis also touch on the circumstance where a pillar is placed in the public domain.  The height, width and even the common use of the pillar contribute to the ruling on whether or not it will be prohibited to establish an eiruv on that pillar.

I love reading passages where a conventional law is superceded by practicality.  When everyone stops to adjust their packages on the pillar in the middle of the square, that action is allowed, regardless of the height or width of the pillar.  It is clear that people will do this action regardless of the rabbi's decree.

The rabbis understood that a delicate balance exists between stringent prohibitions and a functioning society.  If their interpretations and laws are too demanding, the people will not follow those laws. However, if halacha is too lenient or flexible, dafka the people will not follow those laws, either.  Jewish halacha is a gentle see-saw, always attempting to find the perfect balance, never steady for more than a moment.  Continually revisiting halacha, we recreate this very Jewish act of balance between strict and flexible interpretations and demands.
