וְנָבְקָ֤ה רֽוּחַ־מִצְרַ֙יִם֙ בְּקִרְבּ֔וֹ וַעֲצָת֖וֹ אֲבַלֵּ֑עַ וְדָרְשׁ֤וּ אֶל־הָֽאֱלִילִים֙ וְאֶל־הָ֣אִטִּ֔ים וְאֶל־הָאֹב֖וֹת וְאֶל־הַיִּדְּעֹנִֽים׃
埃及人的心神必在裡面耗盡，我必毀壞他們的謀略；他們必去求問偶像、暗中施法的、招魂的和行巫術的。
Rashi
And the spirit of Egypt shall empty out Heb. וְנָבְקָה. His wisdom shall be emptied out. Comp. (infra 24:1) “Empties out (בּוֹקֵק) the land.”
Ibn Ezra
ונבקה And shall fail. Root בקק to empty. Comp. בוקק maketh empty (24:1). נבקה is Niphal of בקק, and is formed like נסבה and it will be wound about1The regular form of the Niphal third person fem. sing. past of בקק and סבב is נָסַבָּה נָבַקָּה, but the reduplication is very often neglected in the verbs עיע. Comp. יָזְמוּ ,וְנָבְלָה (Gen. 11:6,7) from בלל and זטם. (Ez. 41:7).
