Indeed some persons seem to me not unfitly to understand by “these days” the evils themselves, as in other places of divine Scripture evil days are spoken of; not that the days themselves are evil, but the things that are done on them. And they are said to be shortened, because they are less felt, God giving us endurance; so that even though grievous, they are felt as short.
