Charles Ellicott Commentary Job 15:28

"And he hath dwelt in desolate cities, In houses which no man inhabited, Which were ready to become heaps;" — Job 15:28 (ASV)

Which are ready to become heaps. —This completes the description of the haughty tyrant. He dwelt in cities that are to be desolate, or that are desolate, which are ready to become heaps. This may point either to what they were in his intention, or to what he had made them, or to what, in the opinion of the speaker, they were likely to become, despite his having fortified and dwelt in them.
