וְשָׁמְע֧וּ בַיּוֹם־הַה֛וּא הַחֵרְשִׁ֖ים דִּבְרֵי־סֵ֑פֶר וּמֵאֹ֣פֶל וּמֵחֹ֔שֶׁךְ עֵינֵ֥י עִוְרִ֖ים תִּרְאֶֽינָה׃
And in that day shall the deaf hear the words of a book, and the eyes of the blind shall see out of obscurity and out of darkness.
Read midrashic interpretation of Isaiah 29:18: and classical rabbinic exegesis.
