Charles Ellicott Commentary Job 4:20

"Betwixt morning and evening they are destroyed: They perish for ever without any regarding it." — Job 4:20 (ASV)

From morning to evening. — The process is continual and unceasing, and when we consider the ravages of time on history, we may well say, as in Job 4:20, that “none regardeth it.”

The next verse, however, may seem to imply that they themselves are unmindful of their decay, it is so insidious and so complete.
