'Air' in the Bible

When they looked from a distance, they could barely recognize him. They wept aloud, and each man tore his robe and threw dust into the air and on his head.

Then a breath of air passes by my face; it makes the hair of my flesh stand up.

But ask now the beasts, and they shall teach thee; and the fowls of the air, and they shall tell thee:

Seeing it is hid from the eyes of all living, and kept close from the fowls of the air.

One is so near to another, that no air can come between them.
