It is neither fit for the land
 For the manuring of it, when it has lost its savour and spirit; otherwise it makes land fruitful, if too much is not used, and especially fixed salts have this use; though Pliny says F15, 
``every place in which salt is found, it is barren and brings forth nothing.''Nor yet for the dunghill;
 but men cast it out;
 into the streets, as entirely useless: and so such graceless professors and ministers, are to be cast out of the churches of Christ now, and will be excluded the kingdom of heaven hereafter: 
 he that hath ears to hear, let him hear;
 this being a point of great importance and consequence; (See Gill on Matthew 11:15).
