Job 41:25-30

25When Leviathan rises up, the mighty are terrified; they withdraw before his thrashing.26The sword that reaches him has no effect, nor does the spear or dart or arrow.27He regards iron as straw and bronze as rotten wood.28No arrow can make him flee; slingstones become like chaff to him.29A club is regarded as straw, and he laughs at the sound of the lance.130His undersides are jagged potsherds, spreading out the mud like a threshing sledge.
