Commento biblico di Adam Clarke
Isaia 10:15
Shall the axe boast itself against him that heweth therewith? or shall the saw magnify itself against him that shaketh it? as if the rod should shake itself against them that lift it up, or as if the staff should lift up itself, as if it were no wood. No wood "Its master" - I have here given the meaning, without attempting to keep to the expression of the original, לא עץ lo ets, "the no-wood;" that which is not wood like itself, but of a quite different and superior nature. The Hebrews have a peculiar way of joining the negative particle לא lo to a noun, to signify in a strong manner a total negation of the thing expressed by the noun.
"How hast thou given help (ללא כח lelo choach) to the no-strength?
And saved the arm (לא עז lo oz) of the no-power?
How hast, thou given counsel (ללא חכמה lelo chochmah) to the no-wisdom?"
