Apocalypse Explained #317
317. And seven eyes, signifies and who has omniscience. This is evident from the signification of "seven eyes" as being, in reference to the Lord, omniscience; for as "eyes" in reference to man signify the understanding, so in reference to the Lord they signify omniscience. That "eyes" in reference to man signify the understanding, and in reference to the Lord providence, as also Divine wisdom and intelligence, which is omniscience, see above, n. 152. "Seven eyes" are mentioned, because "seven" signifies all things, and is predicated of what is holy (as above).
Lamentations 2:17
17
The LORD hath done that which he had devised; he hath fulfilled his word that he had commanded in the days of old: he hath thrown down, and hath not pitied: and he hath caused thine enemy to rejoice over thee, he hath set up the horn of thine adversaries.
