27 The one who has knowledge uses words with restraint,(A)
    and whoever has understanding is even-tempered.(B)

28 Even fools are thought wise if they keep silent,
    and discerning if they hold their tongues.(C)

18 An unfriendly person pursues selfish ends
    and against all sound judgment starts quarrels.

27 He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit.

28 Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding.

18 Through desire a man, having separated himself, seeketh and intermeddleth with all wisdom.
