Jerome — as excerpted in the Catena Aurea on Matthew 25:1-13

“Suddenly thus, as on a stormy night, and when all think themselves secure, at the hour when sleep is the deepest, the coming of Christ shall be proclaimed by the shout of Angels, and the trumpets of the Powers that go before Him. This is meant when it says, Lo, the bridegroom cometh, go ye out to meet him.”
