Job 17:12 - Ellicott's Commentary On The Whole Bible

They change the night into day. — Comp. Job 11:17. So little did his friends enter into his case that they wanted him to believe that his night of trial was the reverse of darkness, and that there was light at hand. This was to him only the more painful mockery, because of its contrast to his felt condition. He, on the contrary, says that his only hope is in the grave. “The light,” say they, “is near unto the darkness; that it is near before the darkness cometh; they try to persuade me that prosperity is close at hand.”
