It is no wonder that there is such a trembling upon all hearts, such a consternation and great complaining; for it will be a time of no ordinary calamity, but of great evil and misery, in the same sense as it is called a great day, Joe_2:11, great and terrible; and Zep_1:14, &c.; there never was such a day before. It will be a day of trouble to those that are the posterity of Jacob, both good and bad; they shall not be delivered from it, but they shall be delivered out of it.
