הֲיִתְפָּאֵר֙ הַגַּרְזֶ֔ן עַ֖ל הַחֹצֵ֣ב בּ֑וֹ אִם־יִתְגַּדֵּ֤ל הַמַּשּׂוֹר֙ עַל־מְנִיפ֔וֹ כְּהָנִ֥יף שֵׁ֙בֶט֙ וְאֶת־מְרִימָ֔יו כְּהָרִ֥ים מַטֶּ֖ה לֹא־עֵֽץ׃
Should the axe boast itself against him that heweth therewith? Should the saw magnify itself against him that moveth it? As if a rod should move them that lift it up, Or as if a staff should lift up him that is not wood.
