Job 41:25-30

25“The mighty are afraid when Leviathan rises. Broken down, they draw back.

26A sword may strike it but not pierce it. Neither will a spear, lance, or dart.

27It considers iron to be like straw and bronze to be like rotten wood.

28An arrow won’t make it run away. Stones from a sling turn to dust against it.

29It considers clubs to be like stubble, and it laughs at a rattling javelin.

30Its underside is like sharp pieces of broken pottery. It stretches out like a threshing  sledge on the mud.
