Now my days are swifter than a post,.... Or "than a runner" a in a race, in order to obtain the prize; or than one that rides post, or runs on foot to carry a message, such as were Cushi and Ahimaaz; and such are generally swift of foot, or ride on swift horses, who are so employed; and yet Job says his days are swifter, or passed away more swiftly thorn such; meaning either his days in general; or rather particularly his prosperous days, as Mr. Broughton interprets it; these no sooner came but they were gone:
they flee away; like a shadow, or a dream, or a tale that is told:
they see no good; or he saw, perceived, or enjoyed no good in them; not but that he did see and enjoy much good, even much temporal good, which is what is intended; but this was no sooner had than it was taken away, that it was as if it had never been; the evil days of trouble and sorrow, in which he had no pleasure, came so quick upon him.
