Job 41:27

25 When he raiseth up himself, the mighty are afraid: by reason of breakings they purify themselves.

26 The sword of him that layeth at him cannot hold: the spear, the dart, nor the habergeon.

He esteemeth iron as straw, and brass as rotten wood.

28 The arrow cannot make him flee: slingstones are turned with him into stubble.

29 Darts are counted as stubble: he laugheth at the shaking of a spear.

Do read the surrounding verses too, because the context often says more than a single verse.
