4 Bible Verses about Tastelessness

Can food that is tasteless be eaten without salt? Or is there any taste in the white of an egg?

"Salt is good, but if salt loses its flavor, how can its flavor be restored?

"You are the salt of the earth. But if salt loses its flavor, how can it be made salty again? It is no longer good for anything except to be thrown out and trampled on by people.

Salt is good, but if it loses its saltiness, how can you make it salty again? Have salt in yourselves, and be at peace with each other."
