Matthew 18:6-9

But whosoever shall offend one of these little ones who believe in me, it were profitable for him that a great millstone had been hanged upon his neck and he be sunk in the depths of the sea. Woe to the world because of offences! For it must needs be that offences come; yet woe to that man by whom the offence comes! And if thy hand or thy foot offend thee, cut it off and cast it from thee; it is good for thee to enter into life lame or maimed, rather than having two hands or two feet to be cast into eternal fire. And if thine eye offend thee, pluck it out and cast it from thee; it is good for thee to enter into life one-eyed, rather than having two eyes to be cast into the hell of fire.
