For the arrows of the Almighty are within me, the poison whereof drinketh up my spirit: the terrors of God do set themselves in array against me.
Arrows ... within me - have pierced me. A poetic image, representing the avenging Almighty armed with bow and arrows. "Thine arrows stick fast in me" (Psalms 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 (Judges 20:33). All the terrors which the divine wrath can master are set in array against me. "The Lord shall go forth as a mighty man, He shall stir up jealousy like a man of war: He shall cry, yea, roar; He shall prevail against His enemies."
