'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.

7019. 'And Jehovah said to Moses in Midian' means enlightenment and corroboration received from the Divine in that state. This is clear from the consideration that Jehovah was saying to Moses that he should return to Egypt, when in fact Moses had been commanded previously to do so by Jehovah, in Chapter 3:10 and following verses and Chapter 4:12 and following verses, and Moses had already prepared himself, as he had been commanded, for the journey. From this it becomes clear that the command given now means enlightenment and corroboration received from the Divine. The fact that this enlightenment and corroboration was received in that state, that is to say, in a state of truth that goes with simple good, is meant by the detail that Jehovah said what He said to Moses 'in Midian', 'Midian' being truth that goes with simple good.
