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)

301. As regards the second arcanum, if they had been instructed in mysteries of faith they would have perished for ever, meant by the words 'Now by chance he will put out his hand and also take from the tree of life ¹ and eat, and live forever', the position is this: Once people have become reversed orders of life and are unwilling to rely on anything but self and the proprium as the source of their life and wisdom, they are given to reasoning as to whether any matter of faith which they hear about is so or not so. And because self, sensory evidence, and facts are the basis of their reasoning, they inevitably adopt a negative attitude. And when their attitude is negative they also speak blasphemy and practise profanation, and at length do not care whether or not they mingle together unholy things with holy. When man becomes such he stands so condemned in the next life that there is no hope of salvation for him, for the things that have been mingled through acts of profanation remain that way permanently. The moment some idea of what is holy enters in, so does the idea joined to it of what is unholy, and this makes it impossible for that person to live in any but a community of people who are condemned. Anything at all that has been joined to, and is present as, an idea within a person's thought is in the next life perceived very precisely even by spirits in the world of spirits, but more so by angelic spirits. It is perceived so precisely that from merely one idea they know his whole character. Getting rid of unholy things such as are joined on to those that are holy is not possible without hellish torment, which is so intense that if man knew about it he would beware of profanation as of hell itself.
