Revelation 1:7

Behold he cometh with clouds
John carries on the account of Christ in his kingly office, one branch of which is to execute judgment; and describes him by a future coming of his, which cannot be understood of his coming to take vengeance on the Jews, at the time of Jerusalem's destruction, though that is sometimes expressed in such language, and with such circumstances, as here; see ( Matthew 24:30 ) ( 26:64 ) ; because if this revelation was made to John, in the latter end of Domitian's reign, as is commonly reported by the ancients, and in the year 95 or 96, as chronologers generally place it, it must be upwards of twenty years after the destruction of Jerusalem, and therefore cannot relate to that; nor to his coming in a spiritual sense to convert the Jews in the latter day; for this coming is personal, and with clouds, when he will be seen by every eye; all which circumstances do not so well agree with that; besides, all the kindreds of the earth will not lament on that account: the wicked will take little notice of it, the tribes of the Jews will rejoice at it, and so will all the converted Gentiles: it is better therefore to understand this of Christ's second coming to judge the quick and dead, which is represented as just at hand, to denote the certainty of it; and a "behold" is prefixed to it, to excite attention, and to denote the importance of it: things of great moment, and very surprising, will then be done; Christ will appear in great glory and majesty, the dead in Christ will be raised, Christ's personal kingdom will take place, and the general judgment come on. The manner of his coming will be "with clouds"; either figuratively, with angels, who will attend him both for grandeur and service, or literally, in the clouds of heaven; he shall descend in like manner as he ascended, and as Daniel prophesied he should, ( Daniel 7:13 ) . Hence, one of the names of the Messiah, with the Jews, is, (ynne) , "Anani" ^F18, which signifies "clouds"; and his coming is so described, both to denote the grand and magnificent manner, in which he will come, making the clouds his chariots; and to strike terror into his enemies, clouds and darkness being about him, thunder and lightning breaking out of them, as tokens of that vengeance he comes to take upon them; as also the visibility of his coming, he shall descend from the third heaven, where he now is, into the airy heaven, and sit upon the clouds, as on his throne, and be visible to all: hence it follows,

and every eye shall see him;
that is, everyone that has eyes shall see him, or all men shall see him; the righteous shall see him, and be glad; they shall see him in his glory, as he is, and for themselves, and be satisfied; they shall rejoice at the sight of him; they will be filled with joy unspeakable, and full of glory: but the wicked will see him and tremble; they will be filled with the utmost consternation and astonishment; they will not be able to bear the sight of him; they will flee from him, and call to the rocks and mountains to fall on them, and hide them from his face.

And they [also] which pierced him;
his hands, feet, and side, when they crucified him; both the Roman soldiers, who actually did it, and the body of the Jewish nation, the rulers and common people, who consented to it, and at whose instigation it was done; these, being raised from the dead, shall see him with their bodily eyes, whom they so used.

And all kindreds of the earth shall wail because of him;
all the wicked, in the several parts of the world, will lament, and wring their hands, and express the inward terror and horror of their minds, at his appearing; they will fear his resentment of all their wicked words and actions; will dread his wrath, and tremble at his righteous judgment:

even so, Amen,
says John, and so say all true believers; what the wicked lament, they rejoice at; they desire the coming of Christ, they love it, look and long for it; they believe it shall be, and wish it may be quickly, as in ( Revelation 22:20 ) ; This expression of faith in, and desire after the coming of Christ, is signified by two words, the one Greek and the other Hebrew; suggesting, that this is an article of faith among all the saints of all nations, Jews and Gentiles, and is what they are wishing and waiting for.
