Genesis 4:5-7

VIN(i) 5 but to Cain and to his offering he did not look with favor. And Cain became very angry, and his face fell. 6 the LORD said to Cain: "Why are you angry? Why is your face downcast? 7 "If you do what is right, will not your attitude improve? But if you do not do what is right, sin is crouching at your door. It desires to have you, but you must master it."
