'Salt' 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 for cleansing; thou wast not rubbed with salt at all, nor swaddled at all.

and thou shalt present them before Jehovah; and the priests shall cast salt upon them, and they shall offer them up for a burnt-offering unto Jehovah.

But its marshes and its pools shall not be healed; they shall be given up to salt.
