He shall flee from the iron weapon That is, from the sword or spear; and so shall think himself out of danger. The bow of steel Which is of great strength, and therefore sendeth forth the arrow with greater force; shall strike him through Shall mortally wound him. He shall flee from one danger, but another, still greater, shall overtake him. It is drawn Namely, the arrow which had entered into his body, and now is drawn out of it, either by himself or some other person. Yea, the glittering sword Hebrew, וברק, ubarak, literally, the lightning, and thence a glittering weapon, the bright sword, or spear; as Deuteronomy 32:41. By this it is implied he was doubly wounded, first with the arrow, and then with the sword or spear: cometh out of his gall Into which it had entered, and wherewith it was coloured. This shows that the wound was both deep and deadly, as wounds are in that part. It is probable he mentions this in reference to a similar expression of Job 16:13. Terrors are upon him Namely, the terrors of death; because he perceives, by the tincture of his gall upon the weapon, that his wound is incurable. Or horrors of conscience, because he cannot live, and dare not die.
