Genesis 4:3-5

³And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto Jehovah. ⁴And Abel, he also brought of the firstlings of his flock and of the fat thereof. And Jehovah had respect unto Abel and to his offering: ⁵but unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.
