Job 41:25-30

25When it rises up, the mighty are terrified, at its thrashing about they withdraw.

26Whoever strikes it with a sword will have no effect, nor with the spear, arrow, or dart.

27It regards iron as straw and bronze as rotten wood.

28Arrows do not make it flee; slingstones become like chaff to it.

29A club is counted as a piece of straw; it laughs at the rattling of the lance.

30Its underparts are the sharp points of potsherds, it leaves its mark in the mud like a threshing sledge.
