פּירוש אויף ישעיהו 29:12

וְנִתַּ֣ן הַסֵּ֗פֶר עַל֩ אֲשֶׁ֨ר לֹֽא־יָדַ֥ע סֵ֛פֶר לֵאמֹ֖ר קְרָ֣א נָא־זֶ֑ה וְאָמַ֕ר לֹ֥א יָדַ֖עְתִּי סֵֽפֶר׃ (ס)

און אַז דאָס געשריפֿטס װערט געגעבן צו דעם װאָס קען ניט קײן געשריפֿטס, אַזױ צו זאָגן: לײען דאָס, איך בעט דיך, זאָגט ער: איך קען ניט קײן געשריפֿטס.

Rashi

And if the book is given And when they take it from him and open its seal and give it to one who does not understand the language of the letter, and they say to him, “now read this,” he will say, “I cannot read.” Similarly, when you adjure the prince of fire, he will say, “I cannot, for the matter is sealed from me,” and when you adjure his colleague, he will say, “I do not recognize this name, by which you adjure me, for this is not my name.” This is what Jeremiah said (Jer. 21:4): “Behold I will turn around my implements of war that are in your hands.” This refers to the Explicit Name. In Midrash Tehillim (36:5).

Ibn Ezra

And the book is delivered, etc. Neither the wise men nor those that have no intellect will understand this prophecy.18Neither the wise will understand it by their own reasoning, because it is not open to them, nor the rest of the people, because it will not be explained to them by the prophet.
