Genesis 4:4-7

4And Abel, he also brought of the firstlings of his flock and of the fat thereof. And Yhwh had respect unto Abel and to his offering:1

5But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.

6And Yhwh said unto Cain, Why art thou wroth? and why is thy countenance fallen?

7If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.23
