Matthew 18:5-9

And whoso shall receive one such little child in my name receiveth me: but whoso shall cause one of these little ones that believe on me to stumble, it is profitable for him that a great millstone should be hanged about his neck, and that he should be sunk in the depth of the sea. Woe unto the world because of occasions of stumbling! for it must needs be that the occasions come; but woe to that man through whom the occasion cometh! And if thy hand or thy foot causeth thee to stumble, cut it off, and cast it from thee: it is good for thee to enter into life maimed or halt, rather than having two hands or two feet to be cast into the eternal fire. And if thine eye causeth thee to stumble, pluck it out, and cast it from thee: it is good for thee to enter into life with one eye, rather than having two eyes to be cast into the hell of fire.
