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)

8866. 'Who brought you out of the land of Egypt, out of the house of slaves' means deliverance by Him from hell. This is clear from the meaning of 'bringing out' as deliverance; from the meaning of 'the land of Egypt' as molestations by those from hell, dealt with in 7240, 7278; and from the meaning of 'the house of slaves' as spiritual captivity, dealt with in 8049. The reason why 'the house of slaves' means spiritual captivity and also hell is that being held captive by those in hell and being led by them is slavery, whereas being led by the Lord is freedom, 892, 905, 2870-2875, 2882, 2884, 2892, 2893, 6205, 8209. The fact that those belonging to the spiritual Church, who are represented by the children of Israel, were delivered from hell by the Lord, through His coming into the world and making Divine the Human within Himself, see 6854, 6914, 7035, 7828, 7932, 8018, 8321.
