Even so the tongue is a little member,.... Like the bit in the horse's mouth, or like the helm of a ship.And boasteth great things: and does them; for this word may be taken in a good sense: a bridled and sanctified tongue, that is influenced by the grace of God, and directed by the Spirit of God, as it speaks great and good things, it has great power, weight, and influence: the tongue of the just is as choice silver, and the lips of the righteous feed many, Pr 10:20, the Gospel, as preached by Christ's faithful ministers, who are the church's tongue, when it comes not in word only, but in power, is the power of God unto salvation: faith comes by hearing it, and hearing by this word; by it souls are convinced, converted, and comforted, enlightened, quickened, and sanctified.
Behold, how great a matter a little fire kindleth; what vast quantities of wood, large forests, stately buildings, and populous towns and cities, are at once seized on by a little fire, a few sparks, and in a short time burnt down, and utterly destroyed.
