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.
Genesis 3:23-24
23
Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.
24
So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.
