Genesis 4:3-5

New International Version

³ In the course of time Cain brought some of the fruits of the soil as an offering^(A) to the Lord.^{(B) 4} And Abel also brought an offering—fat portions^(C) from some of the firstborn of his flock.^(D) The Lord looked with favor on Abel and his offering,^{(E) 5} but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast.
