John Gill's Exposition of the Whole Bible
Proverbs 15:18
A wrathful man stirreth up strife,.... A man of a wrathful disposition, of a furious spirit, of an angry temper; that is under the power and dominion of such a passion, and indulges it, and takes all opportunities to gratify it; he stirs up strife and contention where there was none, or where it was laid; as a man stirs up coals of fire and raises a flame; see Proverbs 26:21. He stirs up strife in families, sets one relation against another, and the house in an uproar; he stirs up contentions in neighbourhoods, and sets one friend and neighbour against another, whence proceed quarrels and lawsuits: he stirs up strife in churches, breaks brotherly love, and causes animosities and divisions; he stirs up strife in kingdoms and states, whence come wars and fightings, confusion, and every evil work;
but [he that is] slow to anger appeaseth strife: a man of a quiet and peaceable disposition, possessed of the true grace of charity; who is not easily provoked, longsuffering, bears and endures all things; he allays the heat of anger; he quenches the coals of contention; he calms the storm and makes it quiet, as the word o signifies; he
"mitigates strifes raised,''
as the Vulgate Latin version renders it; he composes differences, reconciles the parties at variance, and makes all hush and still; and so prevents the ill consequences of contention and strife.
