Genesis 4:3–10

³After some time, Cain brought some of his harvest and gave it as an offering to the Lord. ^4*Then Abel brought the first lamb born to one of his sheep, killed it, and gave the best parts of it as an offering. The Lord was pleased with Abel and his offering, ⁵but he rejected Cain and his offering. Cain became furious, and he scowled in anger. ⁶Then the Lord said to Cain, “Why are you angry? Why that scowl on your face? ⁷If you had done the right thing, you would be smiling;^u but because you have done evil, sin is crouching at your door. It wants to rule you, but you must overcome it.”

^8*Then Cain said to his brother Abel, “Let’s go out in the fields.”^v When they were out in the fields, Cain turned on his brother and killed him.

⁹The Lord asked Cain, “Where is your brother Abel?”

He answered, “I don’t know. Am I supposed to take care of my brother?”

^10*Then the Lord said, “Why have you done this terrible thing? Your brother’s blood is crying out to me from the ground, like a voice calling for revenge.
