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)

7873. 'And on all the gods of Egypt I will make judgements' means their falsities which are to be damned. This is clear from the meaning of 'gods' as falsities, dealt with below; and from the meaning of 'making judgements' as being damned, for to judge or to make judgements is to point either to life or to death; a judgement that points to life means salvation, one that points to death means damnation. The term 'gods' is used many times in the Word. When angels are called such, truths are meant, see 4295, 4402, 7268, and therefore in the contrary sense 'the gods of the nations' means falsities, 4402, 4544. The reason why truths are referred to as 'gods' is that truth emanates from God Himself and is in itself of God. Consequently those who receive that truth are called 'gods'. Not that they are gods; rather, the truth with them is of God. This explains why in the original language God is referred to by the plural noun Elohim. God Himself is Divine Goodness, but what emanates from Him is Divine Truth which fills the whole of heaven. So then, because 'god' means truth, falsity is meant by that word in the contrary sense.
