Then certain of them came to him, saying, Good Master, we have Moses and the prophets, and whosoever shall live by them, shall he not have life?

 And Jesus answered, saying, Ye know not Moses, neither the prophets; for if ye had known them, ye would have believed on me; for to this intent they were written. For I am sent that ye might have life. Therefore I will liken it unto salt which is good;

 But if the salt has lost its savor, wherewith shall it be seasoned?
