But I don't understand what that means. Can you explain how it matters in the story?
Deeper Explanation of Answer #1
Sure. In this story it means that when someone looses some of their physical well being, you should find a way to restore that which they lost.
Wait, but isn't there another place in the torah that says that?
Yes and I will explain it to you while we go grab something to eat. I'm a little hungry it has been a long day.
Answer to Question #2
The second source is understood as Don't stand next to the loss of blood of your fellow, and not do anything about it.
We also learn that one person is equivalent to a whole world. The deeper explanation is that at first Adam was created and the entire world was in existence around him, so he must have been equivalent to the entire world.
Thanks so much! Now I really understand the Gemara and why you acted like you did. The two sources were also really helpful because they teach me that Even if I can't save the life, I have to do whatever I can to have the life saved.
