By faith, Abel offered unto God a more plenteous sacrifice than Cain: by which he obtained witness that he was righteous, God testifying of his gifts: by which also he being dead, yet speaketh.

and not be as Cain, which was of the devil and slew his brother. And wherefore slew he him? For his own deeds were evil, and his brother's righteous.

Woe be unto them, for they have followed the way of Cain, and are utterly given to the error of Balaam for lucre's sake, and are cast away in the treason of Korah.
