An adjective describing brilliant or dazzling light, appearing in Job's meditation on God's inaccessible glory. The context suggests light so bright it cannot be looked upon directly, seen in the clouds after a clearing storm. This rare term emphasizes not just brightness but a quality of brilliance that overwhelms the eye. Elihu uses it to point toward God's unapproachable radiance, which precedes his description of divine glory coming from the north.
