Genesis 4:3-5

3So it came about 1in the course of time that Cain brought an offering to the Lord from the fruit of the ground.

42Abel, on his part also brought an offering, from the firstborn of his flock and from their fat portions. And 3the Lord had regard for Abel and his offering;

5but 4for Cain and his offering He had no regard. So 5Cain became very angry and his face 6was gloomy.
