Luke 14:34 in the King James Version
Salt is good: but if the salt have lost his savour, wherewith shall it be seasoned?
Context
33 So therefore, whoever of you who doesn’t renounce all that he has, he can’t be my disciple.
34 “Salt is good, but if the salt becomes flat and tasteless, with what do you season it?
35 It is fit neither for the soil nor for the manure pile. It is thrown out. He who has ears to hear, let him hear.”
