John Trapp on Proverbs 28:11

Verſ. 11. The rich man is wiſe in his own conceit] He ſacrificeth to himſelf, as Scianus did; to his drag and net, as the Babylonians did;Scianus ſihi ſacrificabat. Dio. Hab[illegible: 1 letter]k. 1.16 hee thanks his wit for his wealth, and takes upon him as if there were none ſuch. (See 1 Tim. 6.17. with the note there) Like Iſis her Aſſe, that had gone ſo oft to the temple of that Goddeſſe, that at length ſhe thought her ſelf worſhipful. Every grain of riches hath a vermine of pride and ſelf conceit in it, and a very ſmall wind will blow up a bubble.

But the poor that hath underſtanding] That is well verſed in the bigger volume of Gods Word, and in the leſſer volume of his own heart, (which is better to him than any Expoſitor, for the right underſtanding of the Scriptures) this poor wiſe-man ſearcheth him out, finds the rich mans folly, and if need be, tells him of it, giving him a right character of himſelf. Sed divitibus ferè ideo talis amicus deeſt, quia nihil deeſt.
