Genesis 4:6 Meaning and Commentary

Genesis 4:6

And the Lord said unto Cain, why art thou wroth? and why is
thy countenance fallen?
&c.] Which was said not as being ignorant of his wrath and resentment, but to bring him to a conviction of his sin or sins, which were the cause of God's rejecting his sacrifice, and to repentance and amendment; and to show him that he had no cause to be displeased, either with him or his brother, for the different treatment of him and his offering; since the fault lay in himself, and he had none to blame but his own conduct, which for the future he should take care to regulate according to the divine will, and things would take a different turn.

Genesis 4:6 In-Context

4 and Abel also brought [an offering] from {the choicest firstlings of his flock}. And Yahweh looked with favor to Abel and to his offering,

5 but to Cain and to his offering he did not look with favor. And Cain became very angry, and his face fell.

6 And Yahweh said to Cain, "Why are you angry, and why is your face fallen?

7 If you do well {will I not accept you}? But if you do not do well, sin is crouching at the door. And its desire [is] for you, but you must rule over it."

8 Then Cain said to his brother Abel, ["Let us go out into the field."] And when they were in the field, Cain rose up against his brother Abel and killed him.
