'Salted' in the Bible

And as for thy nativity, in the day thou wast born thy navel was not cut, neither wast thou washed in water to cleanse thee; thou wast not salted at all, nor swaddled at all.

Ye are the salt of the earth: but if the salt have lost its savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out and trodden under foot of men.

For every one shall be salted with fire.
