New Defender's Study Bible Notes
30:6 caves of the earth. Job here is referring to what modern paleoanthropologists call the “cavemen.” These were not ape-men, but descendants of those who scattered from Babel and then, for some reason, deteriorated mentally and physically, as well as spiritually. They fled “into the wilderness in former time desolate and waste” (Job 30:3). They were “driven forth from among men” (Job 30:5) by those tribes who competed successfully for the more desirable regions of the earth.
