Job 15:28

“And he dwelleth in desolate cities, etc.] This is either a continuation of the account of the wicked man’s prosperity, which makes him haughty; such is his might and power, that he destroys cities and palaces, built and enjoyed by others, and then out of the ruins of them builds greater cities and more noble palaces, to perpetuate his name to posterity; which sense agrees with (<180314>Job 3:14); and with the Targum, “and he makes tabernacles in desert cities, that he may dwelt in houses which were not inhabited;” and so Ben Gersom: and hence because of his success among men, and the grandeur he lives in, his heart is lifted up, and his hand is stretched out against God; or else this may…”

Instead of living in affluence and in a splendid city, he shall be compelled to take up his abode in places that have been deserted and abandoned. Such places - like Petra or Babylon now - became the temporary lodgings of caravans and travelers, or the abodes of outcasts and robbers. The meaning here is, that the proud and wicked man shall be ejected from his palace, and compelled to seek a refuge far away from the usual haunts of men. Which are ready to become heaps - Which are just ready to tumble into…”

“But - This is fitly opposed to the prosperity last mentioned, and is the beginning of the description of his misery. Job 15:29”

“desolate: Job 3:14, Job 18:15; Isa 5:8-10; Mic 7:18 which are ready: Jer 9:11, Jer 26:18, Jer 51:37; Mic 3:12 Job 15:29”
