"Salt of the earth"

1. Matt. 5: 13
   13 ¶ Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.
2. 3 Ne. 12: 13
   13 Verily, verily, I say unto you, I give unto you to be the salt of the earth; but if the salt shall lose its savor wherewith shall the earth be salted? The salt shall be thenceforth good for nothing, but to be cast out and to be trodden under foot of men.
3. D&C 101: 39-40
   39 When men are called unto mine everlasting gospel, and covenant with an everlasting covenant, they are accounted as the salt of the earth and the savor of men;
   40 They are called to be the savor of men; therefore, if that salt of the earth lose its savor, behold, it is thenceforth good for nothing only to be cast out and trodden under the feet of men.
