The Rabbi and the Gentile Woman
A Rabbi gathered together his students and asked them: “How do we know the exact moment when night ends and day begins?”
“It’s when, standing some way away, you can tell a sheep from a dog,” said one boy.
The Rabbi was not content with the answer.
Another student said: “No, it’s when, standing some way away, you can tell an olive tree from a fig tree.”
“No, that’s not a good definition either.”
“Well, what’s the right answer?” asked the boys.
And the Rabbi said: “When a stranger approaches, and we think he is our brother, that is the moment when night ends and day begins.”
