A man that flatters his neighbor spreads a net for his feet.
In this verse Solomon does not refer solely to the intention of the flatterer; he refers also to the tendency of the flattery. The latter may be far from harmless, even although to a greater degree the former may. Injury may be done, and many a time is done, when no harm is meant to the party, and when there is no interest of our own to serve. And there is no little guilt on the part of those who, seeing vanity to be a man's failing, set themselves on purpose to feed it, pouring into the ear, merely in the way of an amusing experiment, every description of fulsome adulation, trying how much and in what variety it will be taken in.
(R. Wardlaw, D.D.)
