Genesis 4:9-12

Later, the LORD said to Cain, “Where is your brother Abel?” Cain answered, “I don’t know. Is it my job to take care of my brother?” Then the LORD said, “What have you done? Your brother’s blood is crying out to me from the ground. And now you will be cursed in your work with the ground, the same ground where your brother’s blood fell and where your hands killed him. You will work the ground, but it will not grow good crops for you anymore, and you will wander around on the earth.”
