An old Rabbi once asked the pupils how they could tell when night had ended and day had begun.
"Could it be," asked one of the students, "When you can see an animal in the distance and tell whether it is a sheep or a dog?"
"No," answered the Rabbi.
Another asked, "Is it when you can look at a tree in the distance and tell whether it's a fig tree or a peach tree?"
”No," answered the Rabbi.
"Then when is it?" the pupils demanded.
"It is when you can look on the face of any man or woman and see that it is your sister or brother. Because if you cannot see this, it is still night."
