Matthew 18:9
And if your eye causes you to sin, tear it out and throw it away. It is better for you to enter life with one eye than with two eyes to be thrown into the hell of fire. The eye-plucking teaching applied to the chapter's concern: the eye that causes stumbling must be removed. The hell of fire (Gehenna) is the eschatological judgment destination for those who are not protected by the radical self-surgery the previous verses command.
