Wilderness
'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.

Knives of flints
In Joshua 5:2, 3, knives or swords of flint symbolize the truth they needed to absorb in order to discipline and drive away foul passions. Without a knowledge of truth, there can never be any purification. (Arcana Coelestia 2039[8])
