Mark 9:42-48

And whosoever shall cause one of these little ones that believe on me to stumble, it were better for him if a great millstone were hanged about his neck, and he were cast into the sea. And if thy hand cause thee to stumble, cut it off: it is good for thee to enter into life maimed, rather than having thy two hands to go into hell, into the unquenchable fire. And if thy foot cause thee to stumble, cut it off: it is good for thee to enter into life halt, rather than having thy two feet to be cast into hell. And if thine eye cause thee to stumble, cast it out: it is good for thee to enter into the kingdom of God with one eye, rather than having two eyes to be cast into hell; where their worm dieth not, and the fire is not quenched.
