Job 1:9 - Ellicott's Commentary On The Whole Bible

Doth Job fear God for nought? — Manifesting the worst kind of scepticism, a disbelief in human goodness. Satan knows that the motive of an action is its only value, and by incrimination calumniates the motives of Job. The object of the book is thus introduced, which is to exhibit the integrity of human conduct under the worst possible trial, and to show man a victor over Satan.
