Genesis 4:5

Cain was very wroth; partly with God, who, had cast so public a disgrace upon him, and given the preference to his younger brother; and partly with Abel, because he had received more honour from God, and therefore was likely to have more respect and privilege from his parents than himself. His countenance fell; whereas before it was lifted up and cheerful, now it fell down through sense of guilt, disappointment of his hope, shame and grief, and envy at his brother.
