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.
Rashi
And all the kings of the earth, etc. To fulfill that which He said to him, (ibid. verse 12): “Behold I have given you a wise and understanding heart; so that there was none like you before you.”
