Proverbs 22:24,25

Make no friendship with an angry man— "By how much the more devoutly the laws of friendship among good men are to be observed, by so much the more it stands us upon to use all caution, even at the very first, in the prudent election of friends; and, let the dispositions and humours of our friends be what they will, so far as concerns ourselves only, they are by all means to be borne withal: but when they impose a necessity upon us to behave ourselves just as they would have us towards other men, it is a very hard and unreasonable condition of friendship. Wherefore it highly concerns us, as Solomon here admonishes, for the preservation of the peace and safety of our life, that we intermingle not our matters with men of cholerick nature, and such as easily provoke or undertake quarrels and debates; for such kinds of friends will perpetually engage us in contentions and factions, so that we shall be constrained either to break off friendship, or to be wanting to our own personal safety."
