Genesis 4:5-7

Revised Standard Version

⁵ but for Cain and his offering he had no regard. So Cain was very angry, and his countenance fell. ⁶ The Lord said to Cain, “Why are you angry, and why has your countenance fallen? ⁷ If you do well, will you not be accepted? And if you do not do well, sin is couching at the door; its desire is for you, but you must master it.”
