הִנֵּ֥ה עָשִׂ֖יתִי כִּדְבָרֶ֑יךָ הִנֵּ֣ה ׀ נָתַ֣תִּי לְךָ֗ לֵ֚ב חָכָ֣ם וְנָב֔וֹן אֲשֶׁ֤ר כָּמ֙וֹךָ֙ לֹא־הָיָ֣ה לְפָנֶ֔יךָ וְאַחֲרֶ֖יךָ לֹא־יָק֥וּם כָּמֽוֹךָ׃
behold, I have done according to thy word: lo, I have given thee a wise and an understanding heart; so that there hath been none like thee before thee, neither after thee shall any arise like unto thee.
