The Hebrew Book of Job is part of Ketuvim ("Writings") of the Hebrew Bible. Not much is known about Job based on the Masoretic Text. The characters in the Book of Job consist of Job, his wife, his three friends (Bildad, Eliphaz, and Zophar), a man named Elihu, God, and angels (one of whom is named Satan). It begins with an introduction to Job's character-he is described as a blessed man who lives righteously in the Land of Uz. The Lord's praise of Job prompts an angel with the title of "satan" ("accuser") to suggest that Job served God simply because God protected him. God removes Job's protection and gives permission to the angel to take his wealth, his children, and his physical health (but not his life). Despite his difficult circumstances, he does not curse God, but rather curses the day of his birth. And although he anguishes over his plight, he stops short of accusing God of injustice. Job's miserable earthly condition is simply God's will.
