Air
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)
Ezekiel 47:8-11
8
Then he said to me, These waters issue forth toward the eastern region, and shall go down into the Arabah; and they shall go toward the sea; into the sea [shall the waters go] which were made to issue forth; and the waters shall be healed.
9
It shall happen, that every living creature which swarms, in every place where the rivers come, shall live; and there shall be a very great multitude of fish; for these waters are come there, and [the waters of the sea] shall be healed, and everything shall live wherever the river comes.
10
It shall happen, that fishermen shall stand by it: from En Gedi even to En Eglaim shall be a place for the spreading of nets; their fish shall be after their kinds, as the fish of the great sea, exceeding many.
11
But the miry places of it, and its marshes, shall not be healed; they shall be given up to salt.
