Apocalypse Revealed #240
240. Full of eyes in front and in back. This symbolizes the Divine wisdom in the Word.
When eyes are mentioned in application to people, they symbolize the intellect, but when they are mentioned in application to the Lord, they symbolize Divine wisdom (nos. 48, 125). So likewise in application to the Word, as in the present instance, because the Word comes from the Lord, and is about the Lord, and so embodies the Lord.
The same statement is made in reference to the cherubim in Ezekiel, that they were "full of eyes" (Ezekiel 10:12).
"In front and in back," when said of the Word given by the Lord, symbolizes the Divine wisdom and love present in it.
Ezekiel 1:10-11
10
As for the likeness of their faces, they had the face of a man; and the four of them had the face of a lion on the right side; and the four of them had the face of an ox on the left side; the four of them also had the face of an eagle.
11
Such were their faces. Their wings were spread out above. Two wings of each one touched another, and Two covered their bodies.
