3 So it came about in the course of time that Cain brought an offering to the Lord of the fruit of the ground.
4 Abel, on his part also brought of the firstlings of his flock and of their fat portions. And the Lord had regard for Abel and for his offering;
5 but for Cain and for his offering He had no regard. So Cain became very angry and his countenance fell.
6 Then the Lord 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 crouching at the door; and its desire is for you, but you must master it."
8 Cain told Abel his brother. And it came about when they were in the field, that Cain rose up against Abel his brother and killed him.
9 Then the Lord said to Cain, "Where is Abel your brother?" And he said, "I do not know. Am I my brother's keeper?"
