Matthew 5:29-30

Now if your right eye is causing you to sin, tear it out and throw it away from you; for it is better for you to lose one of the parts of your body, than for your whole body to be thrown into hell. And if your right hand is causing you to sin, cut it off and throw it away from you; for it is better for you to lose one of the parts of your body, than for your whole body to go into hell.
