Ecclesiastes 10:10

10:10 If an iron axhead ¹  is blunt and a workman ²  does not sharpen ³  its edge, ⁴ 

he must exert a great deal of effort; ⁵ 

so wisdom has the advantage of giving success.

Isaiah 10:34

10:34 The thickets of the forest will be chopped down with an ax,

and mighty Lebanon will fall. ⁶ 

[10:10]  ¹ tn The term “ax head” does not appear in the Hebrew text, but is supplied in the translation for clarity. The preceding noun “iron” functions as a metonymy of material (i.e., iron) for the object with which it is associated (i.e., ax head).

[10:10]  ² tn Heb “he”; the referent (the workman) is implied, and has been specified in the translation for clarity

[10:10]  ³ tn The verb קלל in the Pilpel means “to sharpen; to make a blade sharp” (HALOT 1104 s.v. קלל 1).This denominative verb is derived from the rare noun II קָלַל “smooth; shiny” (referring to bronze; Ezek 1:7; Dan 10:6; HALOT 1105 s.v.). Sharpening the blade or head of a bronze ax will make it smooth and shiny. It is not derived from I קָלַל (qalal) “to treat light” or the noun I קְלָלָה (qÿlalah) “curse.” Nor is it related to I קָלַל “to shake” (Ezek 21:26); cf. HALOT 1104. BDB 886 s.v. קָלַל 2 erroneously relates it to I קָלַל, suggesting “to whet” or “to move quickly to and fro.”

[10:10]  ⁴ tn Heb “face.”

[10:10]  ⁵ tn Heb “strength.” The term וַחֲיָלִים (vakhayalim, conjunction + plural noun from חַיִל, khayil, “strength; efficiency”) is an example of a plural of intensification (GKC 397-98 §124.e). The point is that it is a waste of a great deal of strength and energy. If a person is not smart, he will have to use a lot of energy and waste his efficiency.

[10:34]  ⁶ tn The Hebrew text has, “and Lebanon, by/as [?] a mighty one, will fall.” The translation above takes the preposition בְּ (bet) prefixed to “mighty one” as indicating identity, “Lebanon, as a mighty one, will fall.” In this case “mighty one” describes Lebanon. (In Ezek 17:23 and Zech 11:2 the adjective is used of Lebanon’s cedars.) Another option is to take the preposition as indicating agency and interpret “mighty one” as a divine title (see Isa 33:21). One could then translate, “and Lebanon will fall by [the agency of] the Mighty One.”
