Isaiah 29:12

כִּֽי־נָסַךְ עֲלֵיכֶם יְהוָה רוּחַ תַּרְדֵּמָה וַיְעַצֵּם אֶת־עֵֽינֵיכֶם אֶת־הַנְּבִיאִים וְאֶת־רָאשֵׁיכֶם הַחֹזִים כִּסָּֽה

For the LORD hath poured out upon you the spirit of deep sleep, And hath closed your eyes; The prophets, and your heads, the seers, hath He covered.

וַתְּהִי לָכֶם חָזוּת הַכֹּל כְּדִבְרֵי הַסֵּפֶר הֶֽחָתוּם אֲשֶֽׁר־יִתְּנוּ אֹתוֹ אֶל־יוֹדֵעַ הספר לֵאמֹר קְרָא נָא־זֶה וְאָמַר לֹא אוּכַל כִּי חָתוּם הֽוּא

And the vision of all this is become unto you as the words of a writing that is sealed, which men deliver to one that is learned, saying: ‘Read this, I pray thee’; and he saith: ‘I cannot, for it is sealed’;

וַיֹּאמֶר אֲדֹנָי יַעַן כִּי נִגַּשׁ הָעָם הַזֶּה בְּפִיו וּבִשְׂפָתָיו כִּבְּדוּנִי וְלִבּוֹ רִחַק מִמֶּנִּי וַתְּהִי יִרְאָתָם אֹתִי מִצְוַת אֲנָשִׁים מְלֻמָּדָֽה

And the Lord said: Forasmuch as this people draw near, and with their mouth and with their lips do honour Me, But have removed their heart far from Me, And their fear of Me is a commandment of men learned by rote;

לָכֵן הִנְנִי יוֹסִף לְהַפְלִיא אֶת־הָֽעָם־הַזֶּה הַפְלֵא וָפֶלֶא וְאָֽבְדָה חָכְמַת חֲכָמָיו וּבִינַת נְבֹנָיו תִּסְתַּתָּֽר

Therefore, behold, I will again do a marvellous work among this people, even a marvellous work and a wonder; and the wisdom of their wise men shall perish, and the prudence of their prudent men shall be hid.
