Behold, the hope of him is in vain: shall not one be cast down even at the sight of him? Behold, the hope of him is in vain: shall not one be cast down even at the sight of him?
The hope - of taking him: or else, 'of any one who tries a battle with him' (Job 41:8).
Is in vain nikzaabaah (H3576) - 'is convicted of a lie;' is proved false.
Cast down - with fear "at the (mere) sight of him."
