Salt is good; but if the salt has lost its savour, with what shall it be seasoned?

Ye are the salt of the earth, but if the salt has lost its savour, with what shall it be salted? From then on it is good for nothing, but to be cast out and to be trodden under foot of men.

Salt is good, but if the salt has lost its saltness, with what will ye season it? Have salt in yourselves, and have peace one with another.
