'Air' in the Bible

And the Philistine said to David, Come to me, and I will give thy flesh unto the fowls of the air, and to the beasts of the field.

This day will the LORD deliver thee into mine hand; and I will smite thee, and take thine head from thee; and I will give the carcases of the host of the Philistines this day unto the fowls of the air, and to the wild beasts of the earth; that all the earth may know that there is a God in Israel.
