Even thus - Destruction came upon the old world, and upon Sodom, "suddenly;" when they were engaged in other things, and little expecting this. "So" suddenly and unexpectedly, says he, shall destruction come upon the Jewish people. See the notes at Matt. 24.

Even thus shall it be in the day when the son of man is revealed. In his power, when he comes to avenge himself on the Jews; and when he is revealed from heaven in flaming fire, at the last day. As in the days of Noah and Lot, men lived in great carnality and security, thoughtless and fearless of danger, so were the Jews before the destruction of their city and temple, buoying themselves up with deliverance to the last; and such will be the times of indolence and supineness, before the coming of the day of the Lord to judgment: and as the destruction of the old world, and men of Sodom, and the adjacent parts, was sudden and unexpected, so was the destruction of Jerusalem, and so will be the burning of the world; that day will come, as a thief in the night: and as in the above calamities, there was a remnant saved, who were taken care of; as Noah and his family in tim ark, and as Lot, and his wife and daughters were snatched out of Sodom, when the rest were destroyed; so when the Christians removed from Jerusalem, and went to Pella, being directed by a divine oracle, then came on the siege of Jerusalem (r); and when all the elect will be gathered in, and brought to faith and repentance, then shall the earth, and the works in it be burnt up: and as these judgments were universal, so was that upon the people of the Jews: and such will be the general desolation in the last day.
