'Wilderness' signifies something with little life in it, as described in the internal sense in Luke 1:80 'Wilderness' signifies somewhere there is no good because there is no truth. 'Wilderness,' as in Jeremiah 23:10, signifies the Word when it is adulterated.

(Reference: Arcana Coelestia 1927)

In Psalm 83:13, this refers to the casting down and subjugation of the hells by the Lord. (Arcana Coelestia 2468; the Inner Meaning of the Prophets and Psalms 333)
