The story is told of a rabbi whose disciples were debating the question of when precisely “daylight” commenced.

One proposed:

“It is when one can see the difference between a sheep and a goat at a distance.”

Another suggested:

“It is when you can see the difference between a fig tree and an olive tree at a distance.”

And so it went on. When they eventually asked the rabbi for his view, he said:

“When one human being looks into the face of another and says: ‘This is my sister’ or ‘this is my brother’ then the night is over and the day has begun.“
