Genesis 4:7-9

New Century Version

⁷ If you do things well, I will accept you, but if you do not do them well, sin is ready to attack you. Sin wants you, but you must rule over it.”

⁸ Cain said to his brother Abel, “Let’s go out into the field.” While they were out in the field, Cain attacked his brother Abel and killed him.

⁹ 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?”
