In The Book of Job God commands Satan to smite Job, a rich but pious man, as a test of his devotion:

Job 1:12. And the LORD said unto Satan, Behold, all that he hath is in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the LORD. 

Satan and the sons of God destroy Job's home, livelihood and offspring. Having lost all his material goods, Job throws himself to the ground and declares:

Job 1:21. Naked came I out of my mother's womb, and naked shall I return thither: the LORD gave, and the LORD hath taken away; blessed be the name of the LORD.
