Genesis 4:3-5King James Version (KJV)

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.
