Mark 9:47-50

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. For every one shall be salted with fire. Salt is good: but if the salt have lost its saltness, wherewith will ye season it? Have salt in yourselves, and be at peace one with another.
