Salt is good, but if the salt has become tasteless, with what shall it be seasoned?
You are the salt of the earth, but if the salt loses its savor, with what shall it be salted? It is no longer good for anything, but to be thrown out and to be trodden underfoot by men.
Let your speech be always with grace, having been seasoned with salt, that you may know how you ought to answer each one.
