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 ,"every place in which salt is found, it is barren and brings forth nothing.'
'Nor yet for the dunghill; to mix with dung, and help it, that it may be the more serviceable for the earth; and just such useless things, are a mere external profession of religion, and professors of it, and ministers of the word, without the grace of God; they are of no use, but hurtful to the church, and to the world; these phrases are left out in the Persic and Ethiopic versions: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 "Mt 11:15".
