'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.

27. The Word’s Literal Sense Is the Foundation, Containing Vessel and Buttress of Its Spiritual and Celestial Meanings

Every Divine work has in it a first, intermediate, and final element, and the first one progresses through the intermediate one to the final one, and so takes form and endures. Thus the final element is the foundation. Moreover, the first element is present in the intermediate one, and present through the intermediate one in the final one. Thus the final element is the containing vessel. And because the final element is the containing vessel and foundation, it is also the buttress.
