Through faith Abel offered to God a more acceptable sacrifice than Cain did, and through this faith he obtained testimony that he was righteous, God giving the testimony by accepting his gifts; and through it, though he is dead, he still speaks.

We are not to resemble Cain, who was a child of the Evil one and killed his own brother. And why did he kill him? Because his own actions were wicked and his brother's actions righteous.

Alas for them; for they have followed in the steps of Cain; for the sake of gain they have rushed on headlong in the evil ways of Balaam; and have perished in rebellion like that of Korah!
