St Matthew 5:29-30

And if thy right eye scandalize thee, pluck it out and cast it from thee. For it is expedient for thee that one of thy members should perish, rather than that thy whole body be cast into hell. And if thy right hand scandalize thee, cut it off, and cast it from thee: for it is expedient for thee that one of thy members should perish, rather than that thy whole body be cast into hell.
