Job.
Job. But I wouldn't say that he expected his troubles. Simply he feared them as the Bible says: For the thing which I greatly feared is come upon me, and that which I was afraid of is come unto me. (Job 3.25)
Yes. Moses is generally credited with having written the book of "Job", and at the time Job was alive, there was 'no one like him on the earth'(Job 2:3)...which Moses certainly would have been. So when Moses wrote Job, he was describing something that had happened in the past, and recounting the events in Job's life, during the time period after the death of Joseph in Egypt, and before Moses was a faithful 'man of God'(Psalm 90 superscription). So by the time Moses was serving God, Job had already come through his ordeal, lived an additional 140 years, and died(Job 42:16+17).
Moses fasted forty days and forty nights on Mt. Sinai.
They were his people. Without them, Moses didn't have a job as a leader.
