Genesis 4:5-8 ▼

5 but for Cain and for his offering He had no regard. So Cain became very angry, and his countenance fell.

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

7 If you do well, will not your countenance be lifted up? And if you do not do well, sin is lying at the door; and its desire is for you, but you must rule over it.”

8 Then Cain spoke to Abel his brother; and it happened when they were in the field, that Cain rose up against Abel his brother and killed him.
