Genesis

And Adam knew Eve his wife. And she conceived and bore Cain, and said, I have gotten a man from the LORD.

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

And in the end of days, it happened, Cain brought to the LORD an offering of the fruit of the ground.

And Abel also brought of the firstlings of his flock and of the fat of it. And the LORD had respect to Abel and to his offering,

but He did not have respect to Cain and to his offering. And Cain glowed with anger, and his face fell.

And the LORD said to Cain, Why have you angrily glowed? And why did your face fall?

If you do well, shall you not be accepted? And if you do not do well, sin crouches at the door; and its desire [is] for you, and you shall rule over it.

And Cain talked with his brother Abel. And it happened when they were in the field, Cain rose up against his brother Abel and killed him.

And the LORD said unto Cain, Where [is] your brother Abel? And he said, I do not know. [Am] I my brother's keeper?

And He said, What have you done? The voice of your brother's blood cries to Me from the ground.
