'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.

1297. 'And let us burn them thoroughly' means the evils that stem from self-love. This is clear from the meaning of 'to burn, a burning, fire, sulphur, and bitumen' in the Word, where they have reference to evil desires, chiefly to those that belong to self-love, as in Isaiah,

Our holy house, and our splendour, where our fathers praised You, has been made into a blaze of fire, and all our pleasant places have been made into a waste. Isaiah 64:11.

In the same prophet,

Conceive chaff, bring forth stubble. Your wind is a fire that will consume you. Thus the peoples will be burnings of lime; [like] thorns cut down they will be burned in the fire. Isaiah 33:11-12.

And there are many other examples besides these. 'Burning' and 'fire' have reference to evil desires because they possess similar characteristics.
