Genesis 3:17-18

17Then God said to Adam, ‘You listened to your wife and you did what she said. You ate fruit from the tree after I told you, “You must not eat fruit from this tree.” Because you did that, I will curse the ground. You will have to work very hard to make plants grow in it for your food. It will be like this for your whole life.

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