GENESIS 4:3-8 (KJV)

³And in process of time it came to pass, that Qayin brought of the fruit of the ground an offering unto YHVH. ⁴And Hevel, he also brought of the firstlings of his flock and of the fat thereof. And YHVH had respect unto Hevel and to his offering: ⁵But unto Qayin and to his offering he had not respect. And Qayin was very wroth, and his countenance fell. ⁶And YHVH said unto Qayin, 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. ⁸And Qayin talked with Hevel his brother: and it came to pass, when they were in the field, that Qayin rose up against Hevel his brother, and slew him.
