לָכֵ֗ן הִנְנִ֥י יוֹסִ֛ף לְהַפְלִ֥יא אֶת־הָֽעָם־הַזֶּ֖ה הַפְלֵ֣א וָפֶ֑לֶא וְאָֽבְדָה֙ חָכְמַ֣ת חֲכָמָ֔יו וּבִינַ֥ת נְבֹנָ֖יו תִּסְתַּתָּֽר׃ (ס)
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.
