Genesis 4:4

Then Moses became very angry and said to Yahweh, “Do not regard their offering! I have not taken a single donkey from them, nor have I done harm to any of them.”

By faith Abel offered to God a better sacrifice than Cain, through which he was approved as being righteous—God approving his gifts—and through faith, though he is dead, he still speaks.

Woe to them! For they have gone the way of Cain, and for pay they have poured themselves into the error of Balaam, and perished in the rebellion of Korah.
