'Air' in the Bible

"And I will summon over them four types of calamity," {declares} Yahweh, "the sword to kill, and the dogs to drag away, and the birds of the air and the wild animals of the earth to devour and to destroy.

"They will die by diseases, they will not be mourned, and they will not be buried. They will be as dung on the face of the earth. And they will perish by the sword and they will perish by the famine. And their dead bodies will become food for the birds of the air, and for the wild animals of the earth."
