Genesis 4:1-5

King James Version

4 And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the Lord.

² And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.

³ And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the Lord.

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

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