John Trapp on Proverbs 20:12

Verſ. 12. The hearing ear, and the ſeeing eye, &c.] There are that have ears to hear, and hear not; that have eyes to ſee, and ſee not: for they are a rebellious houſe, Ezek. 12.2. Now when God ſhall ſay to ſuch, as Iſa. 42.18. Hear yee deaf, and look yee blind, that you may ſee; when hee ſhall give them an obedient ear, and a Scripture-ſearching eye, ſenſes habitually exerciſed to diſcern both good and evil, Heb. 5.14. ſo that they hear a voyce behind them, ſaying, This is the way, &c. and they ſee him that is inviſible, as Moſes: then is it with them as it is written, Eye hath not ſeen, nor ear heard, &c. i. e. Natural eye never ſaw, natural ear never heard ſuch things;1 Cor. 2.9, 10 But God hath revealed them to us by his Spirit.
