Hast thou marked the old way? Hebrew, ארח עולם, orach gnolam, the way of antiquity, that is, of men living in ancient times, or former ages. And, by their way, he either means their course, and common practice, or their end and success. Which were cut down out of time Before their time; who died a violent and untimely death. Whose foundation was overflown, &c. Who, together with their foundation the earth, and all their supports and enjoyments, were destroyed by a flood of waters. As the universal deluge was a most signal and memorable instance of God's displeasure against wickedness and wicked men, and was, doubtless, very well known in those days, Eliphaz takes occasion to enlarge upon it, for five or six verses together, as a proper lesson (so he thought it) for his friend; and then closes it with the mention of another destruction by fire, either past or to be expected, which is described to be as general and as fatal to the wicked.
