Genesis 4:3-8
Read Genesis 4 in full →3So it happened 1in the course of time that Cain brought an offering to Yahweh of the fruit of the ground. 4aAbel, on his part, also brought of the firstborn of his flock and of their fat portions. And bYahweh had regard for Abel and for his offering; 5but afor Cain and for his offering He had no regard. So bCain became very angry, and his countenance fell. 6Then Yahweh said to Cain, “aWhy are you angry? And why has your countenance fallen? 7“aIf you do well, 1will not your countenance be lifted up? bAnd if you do not do well, sin is lying at the door; and its desire is for you, cbut you must rule over it.” 8Then Cain 1spoke to Abel his brother; and it happened when they were in the field, that Cain rose up against Abel his brother and akilled him.
