 In the sweat of your face you shall eat bread until you return to the ground, for out of it you were taken. You are dust, and to dust you shall return. Genesis 3, 17-19 Adam's labor would no longer be easy. Now he had to toil and sweat, and the ground would often produce thorns and thistles instead of fruit. But the greatest curse of all was death. Adam no longer would live forever, but would return to the ground at the end of his life.
