John Trapp on Isaiah 42:18

Ver. 18. Hear ye deaf, and look ye blind] Ye, who as ſo many ſea monſters or deaf Adders, will not hear; and as ſo many blind moles will not ſee, by a perulant blindneſſe, and of obſtinate malice: ſuch were the Scribes and Phariſees who winked hard with their eyes, and wilfully ſhut the windows, leſt the light ſhould come in unto them. See more of this in the Notes on chap. 6. and 29.

That ye may ſee] In nature, Caecorum mens oculatiſſima eſt. We read of Didymus Alexandrinus, that though blind, yet he wrote Commentaries: and of two of Archb. Ʋſhers Aunts, that being blind from their cradles, they taught him firſt to read; ſuch was their readineſſe in the Scriptures: But this was rare; and in ſpirituals it is otherwiſe, till God enlighten both Organ and Object.
