Matthew 5:29-30

Therefore if thy right eye should bring thee occasion to stumble, pluck it out and cast it from thee; for it is better for thee that one of thy members should perish, and not that thy whole body should be cast into hell. And if thy right hand should bring thee occasion to stumble, cut it off, and cast it from thee: for it is better for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
