Several other ancient Mesopotamian texts parallel the Book of Job, including the Sumerian "Man and his God" (remade by the Old Babylonians into "Dialogue between a Man and His God", c. 19th-16th centuries BC) and the Akkadian text, "The Poem of the Righteous Sufferer;" the latter text concerns a man who has been faithful his whole life and yet suffers unjustly until he is ultimately delivered from his afflictions. The ancient poem known as the "Babylonian Theodicy" from 17th-10th centuries BC also features a dialogue between a sufferer and his friend on the unrighteousness of the world.
