From the LCMS website:
Job was a blameless and upright man who came from Uz (Job 1:1), a land northeast of Canaan. The Book of Job examines the depths of his faith, which was severely tested through the sufferings God permitted. Despite the sudden death of his ten children and the loss of all his wealth and his health, Job refused to curse God: “Naked I came from my mother’s womb, and naked shall I return; the LORD gave, and the LORD has taken away; blessed be the name of the LORD” (1:21). Still, in the midst of his tribulations Job questioned the meaning and purpose of suffering to the point of asserting his own righteousness (34:5- 6). Finally, the Lord revealed that a man cannot know the mysteries of God (chapters 38-41). Job’s faith in his Redeemer and the resurrection prevailed (19:25-27). In the end the Lord restored his wealth and blessed him with another seven sons and three daughters.
