By faith Abel offered to God a better sacrifice than Cain did. By faith he was approved as a righteous man, because God approved his gifts, and even though he is dead, he still speaks through his faith.

unlike Cain, who was of the evil one and murdered his brother. And why did he murder him? Because his works were evil, and his brother’s were righteous.

Woe to them! For they have traveled in the way of Cain, have abandoned themselves to the error of Balaam for profit, and have perished in Korah’s rebellion.
