What is the meaning of the biblical idiom: "Job's news"?

Job's news is terrible news! In the Bible, Job starts out the book as both righteous and devout to the Lord. He was very wealthy but still gave thanks to the Lord and prayed for his family in case they sinned. Satan tries to convince the Lord that Job is only righteous because of his wealth and that if the Lord took away all of Job's wealth the man would curse the Lord. So the Lord allowed Satan to kill all of Job's children and destroy all of his herds all in one day. This is the part that refers to the phrase "Job's news."
