Charles Ellicott Commentary Matthew 24:33

"even so ye also, when ye see all these things, know ye that he is nigh, [even] at the doors." — Matthew 24:33 (ASV)

So you also—The pronoun is emphatic. You whom I have chosen, who are therefore among the elect that will be gathered in this way.

The words are spoken to the four Apostles as the representatives of the whole body of believers who would be living—first, at the destruction of Jerusalem, and afterward at the end of the world. Of the four, St. John alone, so far as we know, survived the destruction of Jerusalem.

That it is near—Better, He is near, in accordance with James 5:9.
