Genesis 4:5-12

5but upon Cain and his offering He did not look favorably. Cain became very angry, and his countenance fell.

6Then Adonai said to Cain, “Why are you angry? And why has your countenance fallen?

7If you do well, it will lift. But if you do not do well, sin is crouching at the doorway. Its desire is for you, but you must master it.”

8Cain spoke to Abel his brother. While they were in the field, Cain rose up against Abel his brother and killed him.

9Then Adonai said to Cain, “Where is Abel, your brother?” “I don’t know,” he said. “Am I my brother’s keeper?”

10Then He said, “What have you done? The voice of your brother’s blood is crying out to Me from the ground.

11So now, cursed are you from the ground which opened its mouth to receive your brother’s blood from your hand.

12As often as you work the ground, it will not yield its crops to you again. You will be a restless wanderer on the earth.”
