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)

1955. 'For she said, Have I not also here seen after Him who sees me?' means influx into the life of the exterior man without the rational serving as a go-between. This is clear from 'seeing after one who sees'. 'Seeing after one who sees' is seeing from that which is interior or higher. In the internal sense that which is inward or higher is expressed in the sense of the letter as after when what is inside or higher is manifesting itself in what is outward or lower. It is Hagar who is speaking here, and she, as shown already, means the life possessed by knowledge and belonging to the exterior man. Since it was that life from which the first rational sprang, the Lord therefore saw the reason why it did so; He saw it from His Interior Man within the Exterior Man, and without the Rational serving as a go-between. Anyone may see that these words embody arcana, if only from the consideration that nobody is able to know what is meant by seeing after Him who sees me except from the internal sense, where matters such as this are present which cannot be explained intelligibly except by means of ideas like those that angels have. These ideas do not fall into words, only into the sense conveyed by words - abstractedly, quite apart from the material ideas out of which the ideas come that belong to the sense conveyed by the words. These matters, which seem so obscure to man, present to the angels ideas so clear and distinct, ideas enriched by so many representations, that if anyone wrote about just a tiny fraction of them he would fill a whole book.
