Go from the presence of a foolish man, when thou perceivest not [in him] the lips of knowledge.
Ver. 7. Go from the presence of a foolish man.] If he be a proud fool, as Proverbs 14:6, a scorner and derider of good counsel, and one that knows not how to lisp out the least syllable of savoury language, break off society with such as soon as may be; for what good can be gotten by their company or conference? "Do men gather grapes of thorns, or figs of thistles?" They infect the very air they breathe upon, and are therefore called λοιμοι, pests, a according to the Septuagint, Psa 1:1 their tongues have the very plague in them; "their breath as fire shall devour you." Isa 33:11 Non potest vir ille sine convitiis quenquam a quo dissentit vel in levissimis, nominare, saith Dr Rivet concerning Bishop Montague; that man hath not the power to forbear railing at any one that dissents from him, though in never so small a matter. Is there any good to be gotten by such? Do not "their words eat as a gangrene." 2Ti 2:17
a Dabhar a word, Debher a pest.
