Wings
'To cover under wings,' as in Psalms 91:4, signifies guarding with the divine truth, which is the divine spiritual. 'Wings' signify spiritual truths. 'Wings,' when related to the Lord, signify the divine spiritual. In the opposite sense, 'wings' relate to falsities and rationalizations from them.

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.
