To be behind, (Genesis 18:10), signifies not to be joined together, but at his back. What is separated from any one, this is represented in another life, by a kind of rejection, as it were, to the back. (Arcana Coelestia 2196)

In Genesis 19:17, this signifies being away from doctrinal things. (Arcana Coelestia 2417)

In Genesis 16:13, Here, behind, or after, signifies within or above, or an interior or superior principle.

In Revelation 1:10, 'behind' signifies that people who do not approach the Lord only (Apocalypse Revealed 42)

41. "Ephesus and Smyrna, Pergamum and Thyatira, Sardis, Philadelphia and Laodicea." This symbolically means, in every case according to each one's state of reception.

That these seven names symbolize, in the spiritual sense, all states of reception for the Lord and His church is something we will see below. For when John received this command, he was in a spiritual state, and in that state nothing is mentioned by name that does not symbolize some thing or state. Consequently the messages written by John were not sent to any church in those places, but were addressed to their angels, meaning people who receive.

That all names of places and persons throughout the Word have spiritual meanings is something we showed many times in Arcana Coelestia (The Secrets of Heaven), published in London. For example, the names of Abraham, Isaac, and Jacob, called also Israel, and the names of his twelve sons. The names also of various places in the land of Canaan, and of places round about that land, such as Egypt, Syria, Assyria, and more.

The same is the case with these seven names. However, for one who wishes to stay with the literal meaning, let him stay with it, because that meaning conjoins. Only let him know that by these names angels perceive matters and states having to do with the church.
