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.
Say
As with many common verbs, the meaning of “to say” in the Bible is highly dependent on context. Who is speaking? Who is hearing? What is it about? Is it a command, a message, an apology, instruction? All these things enter into the meaning of “say.” In general, though, “saying” has to do with sharing truth at various levels -- from the most exalted power people can have to perceive the Lord's desires directly to the most basic of orders issued to people at their lowest.
