וַתִּבְטְחִ֣י בְרָעָתֵ֗ךְ אָמַרְתְּ֙ אֵ֣ין רֹאָ֔נִי חָכְמָתֵ֥ךְ וְדַעְתֵּ֖ךְ הִ֣יא שׁוֹבְבָ֑תֶךְ וַתֹּאמְרִ֣י בְלִבֵּ֔ךְ אֲנִ֖י וְאַפְסִ֥י עֽוֹד׃
And thou hast been secure in thy wickedness, Thou hast said: ‘None seeth me’; Thy wisdom and thy knowledge, It hath perverted thee; And thou hast said in thy heart. ’I am, and there is none else beside me.’
