COMMON salt is known in chemistry by the term sodium chloride. It has been in common use as a flavoring and preserving substance from the earliest times. We read in Job, "Can that which is unsavory be eaten without salt?" The Romans formerly used salt as money. It was called by them "salarium," from which comes our word "salary"—and doubtless the proverb, "He is not worth his salt," that is, "he is not worth his salary." Salt money—cakes of salt—is used in Abyssinia and Tibet at the present. "Salt-horse" is a slang term of sailors for salted beef. "Salt-foot" was a large salt-cellar placed midway on the tables in old baronial halls to separate the noble and favored guests from the vulgar. From this arose the expressions "above the salt" or "below the salt," the former denoting a favored position; the latter, the opposite. Look up by a concordance or Bible index the places where salt occurs in the Scriptures.
