Charles Ellicott Commentary Acts 1:11

"who also said, Ye men of Galilee, why stand ye looking into heaven? this Jesus, who was received up from you into heaven shall so come in like manner as ye beheld him going into heaven." — Acts 1:11 (ASV)

Shall so come in like manner as you have seen him go into heaven.—So our Lord, following the great prophecy of Daniel 7:13, had spoken of Himself as coming in the clouds of heaven (see Note on Matthew 26:64), in visible majesty and glory. Here, again, men have asked questions which they cannot answer; not only, when will the end be, but where will the Judge thus appear? What place will be the chosen scene of His second Advent? So far as we dare to localize what is left undefined, the words of the angels suggest the same scene, as well as the same manner.

Those who do not shrink from taking the words of prophecy in their most literal sense have seen in Zechariah 14:4 an intimation that the Valley of Jehosophat (= Jehovah judges)—the valley of decision—will witness the great Assize, and that the feet of the Judge will stand upon the Mount of Olives, from which He had ascended into heaven. This was the current medieval view, and seems, if we are to localize at all, to be more probable than any other.
