The Rabbi put this question to his students: "How can you tell when night has ended and the day has begun?"
One student suggested: "Could it be when you see an animal and you can tell whether it is a sheep or a goat?"
"No, that's not it," answered the rabbi.
Another student said: "Could it be when you look at a tree in the distance and you can tell whether it is a fig tree or a peach tree?"
Again the rabbi answered: "No."
After a few more guesses the students said: "Well, please tell us when night has ended?"
The rabbi answered: "It is when you look on the face of another human and there is enough light to recognize them as your brother or sister."
"Until then, it is night, and the darkness is still with us".
