'Wing' in the Bible

With outstretched wings five cubits wide; the distance from the edge of one wing to the edge of the other was ten cubits.

Their outstretched wings were twenty cubits across; one wing, five cubits long, touching the wall of the house, and the other, of the same size, meeting the wing of the other winged one.

And in the same way, the wings of the other, five cubits long, were stretched out, one touching the wall and the other meeting the wing of the first winged one.

Is the wing of the ostrich feeble, or is it because she has no feathers,

And I have put my hands on the wealth of the peoples, as on the place where a bird has put her eggs; and as a man may take the eggs from which a bird has gone, so I have taken all the earth for myself: and not a wing was moved, and not a mouth gave out a sound.
