Genesis 4:7-14

You will be accepted if you do what is right. But if you refuse to do what is right, then watch out! Sin is crouching at the door, eager to control you. But you must subdue it and be its master.” One day Cain suggested to his brother, “Let’s go out into the fields.” And while they were in the field, Cain attacked his brother, Abel, and killed him. Afterward the LORD asked Cain, “Where is your brother? Where is Abel?” “I don’t know,” Cain responded. “Am I my brother’s guardian?” But the LORD said, “What have you done? Listen! Your brother’s blood cries out to me from the ground! Now you are cursed and banished from the ground, which has swallowed your brother’s blood. No longer will the ground yield good crops for you, no matter how hard you work! From now on you will be a homeless wanderer on the earth.” Cain replied to the LORD, “My punishment is too great for me to bear! You have banished me from the land and from your presence; you have made me a homeless wanderer. Anyone who finds me will kill me!”
