'Salted' in the Bible

As for your birth, in the day you were born your navel was not cut, neither were you washed in water to cleanse you; you weren't salted at all, nor swaddled at all.

"You are the salt of the earth, but if the salt has lost its flavor, with what will it be salted? It is then good for nothing, but to be cast out and trodden under the feet of men.

For everyone will be salted with fire, and every sacrifice will be seasoned with salt.
