Job 39:13 - Ellicott's Commentary On The Whole Bible

Gavest thou the goodly wings unto the peacocks? — Rather, The wing of the ostrich is superb, but are her pinions and her feathers like the stork’s? Ostrich feathers are said to be worth from £8 to £15 a pound; but, beautiful and valuable as they are, they are hardly like the plumage of a bird, and are not so used for flight; on the contrary, the ostrich runs like a quadruped, it is stated at the rate sometimes of fifty or sixty miles an hour.
