Genesis 3:18-19

18Thorn bushes and thistles will grow in the ground. But you will eat plants that grow in the fields.

19You will have to work hard for a long time before you have any food to eat. You will do this for your whole life until you die. Then you will return into the ground. That is where you came from. I made you from the soil of the ground, and you will become soil again.’
