Genesis:4:1-5
rsv@Genesis:4:1 @ Now Adam knew Eve his wife, and she conceived and bore Cain, saying, "I have gotten a man with the help of the LORD."
rsv@Genesis:4:2 @ And again, she bore his brother Abel. Now Abel was a keeper of sheep, and Cain a tiller of the ground.
rsv@Genesis:4:3 @ In the course of time Cain brought to the LORD an offering of the fruit of the ground,
rsv@Genesis:4:4 @ and Abel brought of the firstlings of his flock and of their fat portions. And the LORD had regard for Abel and his offering,
rsv@Genesis:4:5 @ but for Cain and his offering he had no regard. So Cain was very angry, and his countenance fell.
