Genesis 4:1-5

Now Adam had slept with his wife, and she conceived and bore a son named Cain. She said, “By the grace of YAHWEH I have birthed a man!” Then later, she gave birth to Cain’s brother Abel. Abel grew up to be a shepherd, and Cain became a farmer, working the ground. After some time passed, Cain presented an offering to YAHWEH from the produce of the land. Abel also brought his offering, from among the finest of the firstborn of his flocks. YAHWEH was very pleased with Abel and accepted his offering, but with Cain and his offering, YAHWEH was not pleased, making Cain very furious and resentful.
