4And Abel also brought an offering—fat portions from some of the firstborn of his flock. The LORD looked with favor on Abel and his offering,
5but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast. 6Then the LORD said to Cain, “Why are you angry? Why is your face downcast?
7If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.”
