See here, 1. What the scorner does. It is implied that he sows discord and makes mischief wherever he comes. Much of the strife and contention which disturb the peace of all societies is owing to the evil interpreter (as some read it), that construes every thing into the worst, to those that despise and deride every one that comes in their way and take a pride in bantering and abusing all mankind. 2. What is to be done with the scorner that will not be reclaimed: Cast him out of your society, as Ishmael, when he mocked Isaac, was thrust out of Abraham's family. Those that would secure the peace must exclude the scorner.

Cast out the scorner,.... That makes a mock at sin, a jest at religion, and scoffs at all good men, and everything serious and spiritual; cast such an one out of all company and conversation; out of the family, as mocking Ishmael was cast out of Abraham's family; and out of the church, and all religious societies. Jarchi interprets it of the evil imagination or corruption of nature; but this will continue with a man as long as he lives, and, though it may be weakened and subdued, it is not cast out;

and contention shall go out; yea, strife and reproach shall cease; which are caused by the scorner, who stirs up contention and strife in all company where he is, in families, and churches; and is continually casting reproach on good men and things; but, when he is cast out, everything of this nature ceases, and peace and love take place.

Cast out--or drive away. Scorners foster strife by taunts and revilings.
