Proverbs 28:11

11 A rich man deems himself wise; But a poor man that hath understanding searcheth him out, or, as we have translated, Pro 18:17, goes to the bottom of him, whereby is probably thought of the case that he seeks to use him as a means to an ignoble end. The rich man appears in his own eyes to be a wise man, i.e., in his self-delusion he thinks that he is so; but if he has anything to do with a poor man who has intelligence, then he is seen through by him. Wisdom is a gift not depending on any earthly possession.

Note, 1. Those that are rich are apt to think themselves wise, because, whatever else they are ignorant of, they know how to get and save; and those that are purse-proud expect that all they say should be regarded as an oracle and a law, and that none should dare to contradict them, but every sheaf bow to theirs; this humour is fed by flatterers, who, because (like Jezebel's prophets) they are fed at their table, cry up their wisdom. 2. Those that are poor often prove themselves wiser than they: A poor man, who has taken pains to get wisdom, having no other way (as the rich man has) to get a reputation, searches him out, and makes it to appear that he is not such a scholar, nor such a politician, as he is taken to be. See how variously God dispenses his gifts; to some he gives wealth, to others wisdom, and it is easy to say which of these is the better gift, which we should covet more earnestly.
