Matthew 18:16

Mat. 18:16. "And if he will not hear thee, then take with thee one or two more; that, in the mouth of two or three witnesses, every word may be established." It is evident from the next verse, that the end of bringing these others, is that he may hear them and be convinced of the evil of what he has done, and not to entrap him in his words. They are come indeed as witnesses, that is, as witnesses of the evil of what he has done (for witnesses in scripture phrase are not only of facts). It is this only that is wanted; they are come because he will not hear the first, that he may hear when the voice of two or three concur in the matter; it is this that wants to be established, it is the main and the joint voice of several, has the same tendency to establish such wishing, when they jointly bear testimony of the evil of a thing, as in bearing testimony to a fact; the end of their joining together therefore is, that every word of their admonition may be heard; this is evidently the meaning of the place.
