This term appears in a textually difficult passage in Job and likely refers to darkness or deep gloom. BDB suggests reading it as a noun meaning 'darkness' in Job 11:17, where Zophar promises Job that his life will be brighter than noonday, and even what seems like darkness will become like morning. The French gloss 'voler' (to fly) may reflect an alternate interpretation connecting it to a verbal root, but the context strongly supports the meaning 'darkness' as the opposite of morning light. The passage offers hope that Job's dark circumstances will give way to brightness.
