4 Bible Verses about Tastelessness

Will a man take food which has no taste without salt? or is there any taste in the soft substance of purslain?

For salt is good, but if the taste goes from it, of what use is it?

You are the salt of the earth; but if its taste goes from the salt, how will you make it salt again? it is then good for nothing but to be put out and crushed under foot by men.

Salt is good; but if the taste goes from it, how will you make it salt again? Have salt in yourselves, and be at peace one with another.
