John Trapp on Proverbs 11:12

Verſ. 12. Hee that is void of wiſdome deſpiſeth his neighbour] Not remembring that hee is his neighbour, cut out of the ſame cloth, the ſhears onely going between, and as capable of Heaven as himſelf, though never ſo poor, mean, deformed, or otherwiſe deſpicable. None but a fool will do ſo, none but hee that hath a baſe and beggarly heart of his own, as the words ſignifie.

But a man of underſtanding holdeth his peace] That is, refraineth his tongue from ſuch opprobrious language, ſpeaketh the beſt hee can of another, thinks with himſelf, Aut ſumus, aut fuimus, aut poſſumus eſſe quod hic eſt. Or if himſelf bee ſlighted or reviled, objecta probra digno ſupplicio punit, feſtivo ſcilicet contemptu & oblivione, vel ſi tanti eſt, miſericordia elevat. Hee knows it is to no purpoſe, to waſh off dirt with dirt, and is therefore as a dumb man, &c.
