4. arrows . . . within me--have pierced me. A poetic image representing the avenging Almighty armed with bow and arrows (Ps 38:2, 3). Here the arrows are poisoned. Peculiarly appropriate, in reference to the burning pains which penetrated, like poison, into the inmost parts--("spirit"; as contrasted with mere surface flesh wounds) of Job's body.
      set themselves in array--a military image (Jud 20:33). All the terrors which the divine wrath can muster are set in array against me (Isa 42:13).
