Job 41:25-30

25When Leviathan rises, the mighty are terrified; they withdraw because of his thrashing.

26The sword that reaches him will have no effect, nor will a spear, dart, or arrow.

27He regards iron as straw, and bronze as rotten wood.

28No arrow can make him flee; slingstones become like stubble to him.

29A club is regarded as stubble, and he laughs at the sound of a javelin.

30His undersides are jagged potsherds, spreading the mud like a threshing sledge.
