Apocalypse Revealed #246
246. Were full of eyes within. This symbolizes the Divine wisdom in the Word in its natural sense, springing from its spiritual and celestial meanings.
To be shown that living creatures full of eyes in front and in back symbolize the Divine wisdom in the Word, see no. 240 above. The wings being full of eyes has the same meaning here. Moreover, because the Divine wisdom in the natural sense of the Word derives from its spiritual and celestial meanings that lie within, therefore we are told that the wings were full of eyes within.
For more on the spiritual and celestial meanings which exist within every constituent of the Word, see The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 5-26.
Ezekiel 1:23-24
23
Under the expanse were their wings straight, the one toward the other: each one had two which covered on this side, and every one had two which covered on that side, their bodies.
24
When they went, I heard the noise of their wings like the noise of great waters, like the voice of the Almighty, a noise of tumult like the noise of an army: when they stood, they let down their wings.
