Matthew 5:29-30

If your right eye causes you to stumble, pluck it out and throw it away from you. For it is more profitable for you that one of your members should perish than for your whole body to be cast into Gehenna. If your right hand causes you to stumble, cut it off, and throw it away from you. For it is more profitable for you that one of your members should perish, than for your whole body to be cast into Gehenna.
