shabbat 35

at the end of the day, is it about sight or sound?

seeing 2 stars in the sky, birds coming back to nest, or the sun just above the treetops.

or listening to the shofar being blasted from the rooftops?

sight or sound?
either way, twilight comes from above.

(discussion about twilight, and the beginning of shabbat. different opinions about observation of various natural phenomenon - 2 stars, birds coming back to nest, sun just above the treetops. & the communal 6 shofar blasts in the countdown to shabbat. for english translation of this talmud page, see here)
