Gn 4:1-7

Cain and Abel. 1The man had intercourse with his wife Eve, and she conceived and gave birth to Cain, saying, “I have produced a male child with the help of the LORD.”^* 2Next she gave birth to his brother Abel. Abel became a herder of flocks, and Cain a tiller of the ground.^* 3In the course of time Cain brought an offering to the LORD from the fruit of the ground, 4while Abel, for his part, brought the fatty portion^* of the firstlings of his flock.^a The LORD looked with favor on Abel and his offering, 5but on Cain and his offering he did not look with favor. So Cain was very angry and dejected. 6Then the LORD said to Cain: Why are you angry? Why are you dejected? 7If you act rightly, you will be accepted;^* but if not, sin lies in wait at the door: its urge is for you, yet you can rule over it.^b
