Prov 18:1 An unfriendly man pursues selfish ends; he defies all sound judgment.

Prov 18:2 A fool finds no pleasure in understanding but delights in airing his own opinions.

A complete contrast to v15.

A fool finds no pleasure in understanding – ‘He has no true delight in it; it is only to please his friends or save his credit; he does not love his book, nor his business, nor his Bible, nor his prayers; he would rather be playing the fool with his sports.’ (MHC)

delights in airing his own opinions – ‘Self-assertion, talking about himself and his own opinions, is his highest joy.’ (Barnes)

Taking the two parts of this (antithetical) proverb together, we see that the fool’s opinions – so readily imposed on others – simply reveal a vacant mind.

Prov 18:3 When wickedness comes, so does contempt, and with shame comes disgrace.

Prov 18:11 The wealth of the rich is their fortified city; they imagine it an unscalable wall.

Prov 18:12 Before his downfall a man’s heart is proud, but humility comes before honor.

  3. pride of place
  4. pride of pace
  5. pride of grace.
