Matthew Henry and continuators on Proverbs 22:10

10 Cast out the scorner, and contention shall go out; yea, strife and reproach shall cease.

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.
