Animals in the Bible generally refer to spiritual activity, the things we actually do on a spiritual level. "Cattle," as typically used in the Bible, mean a collection of domesticated animals owned by one person or group (including other animals along with cows). It makes sense, then, that cattle would represent the spiritual activities we "own" and have "domesticated."

What are the good things we like to see in ourselves and encourage? What true ideas do we keep in mind, ponder, and use in our decision-making? These can come in great varieties and from many different sources, just as a variety of animals could be part of "cattle," but the key is that we own them, care for them and use them.

Air" in the Bible represents thought, but in a very general way – our capacity to perceive ideas and the way we tend to think, rather than our specific ideas about specific things. We see the world around us through the air, and seeing corresponds to understanding. We hear through the air, and hearing corresponds to being taught and obeying. Birds fly in the air, and they represent specific thoughts and ideas. And breathing itself – taking in air and passing oxygen to the blood – represents our understanding of true spiritual ideas.

In Genesis 1:26, when used with fowls or birds of the air refers to the air we breathe, but sky, or heavens where are stars, and together these terms refer to both the spiritual and natural man, and to their food, or goods and truths. (Arcana Coelestia 57, 58)

In Genesis 3:8, the only Old Testament reference to air is in the phrase "cool of the day" (at the time of the evening breeze) which signifies the period when the church still had some spiritual perception. (Arcana Coelestia 221)

In Revelation 9:2; 16:17, air signifies the divine truth, darkened by infernal falsities. (Apocalypse Explained 541, Apocalypse Revealed 423)

In Revelation 16:17, everyone in the spiritual world breathes air according to his faith. (Apocalypse Revealed 708, Apocalypse Explained 1012, Apocalypse Revealed 708)
