Matthew 5:29-30

If your right eye makes you stumble and leads you to sin, tear it out and throw it away [that is, remove yourself from the source of temptation]; 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. If your right hand makes you stumble and leads you to sin, cut it off and throw it away [that is, remove yourself from the source of temptation]; for it is better for you to lose one of the parts of your body than for your whole body to go into hell.
