John Calvin on Matthew 25:6-7

6. At midnight a cry arose. With respect to the cry I view it as taken metaphorically for his sudden arrival; for we know, that when any thing new and unexpected happens, men are wont to make a loud noise. True, indeed, our Lord cries daily, that he will come quickly, (Revelation 22:20;) but at that, time, the whole frame of the world will resound with the cry, and his dreadful majesty will fill heaven and earth in such a manner, as not only to awaken those who are asleep, but to bring the dead out of their graves, (John 5:28.)
