"From the sweat of your...."

Do you know the saying: From the sweat of your brow you shall eat? Well I just came across the first time we find this in the torah. Towards the end of the fourth aleyah in Bereshis it says "From the sweat of your brow you shall eat bread." Now think what this was like for Adam and Chava. They found everything they ever needed on trees and now they have to use a plow and hoe to harvest their own crops in order to survive! They did it though. This teaches us even the most spoiled of people can turn there lives around and become respectable employed human beings.
