Context
7 If you do well, won’t it be lifted up? If you don’t do well, sin crouches at the door. Its desire is for you, but you are to rule over it.”
8 Cain said to Abel, his brother, “Let’s go into the field.” While they were in the field, Cain rose up against Abel, his brother, and killed him.
9 The LORD said to Cain, “Where is Abel, your brother?” He said, “I don’t know. Am I my brother’s keeper?”
