Matthew 5:29-30

And if your right eye causes you to stumble, gouge it out and throw it away! It is better for you that one part of your body should be destroyed, than that your whole body be thrown into Gehenna. And if your right hand causes you to stumble, cut it off and throw it away! It is better for you that one part of your body should be destroyed, than that your whole body go into Gehenna.
