Genesis 4:8-12

Cain told Abel his brother. And it came about when they were in the field, that Cain rose up against Abel his brother and killed him. Then the LORD said to Cain, “Where is Abel your brother?” And he said, “I do not know. Am I my brother’s keeper?” He said, “What have you done? The voice of your brother’s blood is crying to Me from the ground. Now you are cursed from the ground, which has opened its mouth to receive your brother’s blood from your hand. When you cultivate the ground, it will no longer yield its strength to you; you will be a vagrant and a wanderer on the earth.”
