Ver. 30 And then shall appear the sign of the son of man in heaven, &c.] Not the sound of the great trumpet, mentioned in the following verse; nor the clouds of heaven in this; nor the sign of the cross appearing in the air, as it is said to do in the times of Constantine: not the former; for though to blow a trumpet is sometimes to give a sign, and is an alarm; and the feast which the Jews call the day of blowing the trumpets, ( Numbers 29:1 ) is, by the Septuagint, rendered (hmera shmasiav) , "the day of signification"; yet this sign is not said to be sounded, but to appear, or to be seen, which does not agree with the sounding of a trumpet: much less can this design the last trumpet at the day of judgment, since of that the text does not speak; and, for the same reason, the clouds cannot be meant in which Christ will come to judgment, nor are clouds in themselves any sign of it: nor the latter, of which there is no hint in the word of God, nor any reason to expect it, nor any foundation for it; nor is any miraculous star intended, such as appeared at Christ's first coming, but the son of man himself: just as circumcision is called the sign of circumcision, ( Romans 4:11 ) and Christ is sometimes called a sign, ( Luke 2:34 ) as is his resurrection from the dead, ( Matthew 12:39 ) and here the glory and majesty in which he shall come: and it may be observed, that the other evangelists make no mention of the sign, only speak of the son of man, ( Mark 13:26 ) ( Luke 21:27 ) and he shall appear, not in person, but in the power of his wrath and vengeance, on the Jewish nation which will be a full sign and proof of his being come: for the sense is, that when the above calamities shall be upon the civil state of that people, and there will be such changes in their ecclesiastical state it will be as clear a point, that Christ is come in the flesh, and that he is also come in his vengeance on that nation, for their rejection and crucifixion him, as if they had seen him appear in person in the heavens. They had been always seeking a sign, and were continually asking one of him; and now they will have a sign with a witness; as they had accordingly. And then shall the tribes of the earth, or land, mourn; that is, the land of Judea; for other lands, and countries, were not usually divided into tribes, as that was; neither were they affected with the calamities and desolations of it, and the vengeance of the son of man upon it; at least not so as to mourn on that account, but rather were glad and rejoiced: and they shall see the son of man coming in the clouds of heaven, with power and great glory. The Arabic version reads it, "ye shall see", as is expressed by Christ, in ( Matthew 26:64 ) . Where the high priest, chief priests, Scribes, and elders, and the whole sanhedrim of the Jews are spoken to: and as the same persons, namely, the Jews, are meant here as there; so the same coming of the son of man is intended; not his coming at the last day to judgment; though that will be in the clouds of heaven, and with great power and glory; but his coming to bring on, and give the finishing stroke to the destruction of that people, which was a dark and cloudy dispensation to them: and when they felt the power of his arm, might, if not blind and stupid to the last degree, see the glory of his person, that he was more than a mere man, and no other than the Son of God, whom they had despised, rejected, and crucified; and who came to set up his kingdom and glory in a more visible and peculiar manner, among the Gentiles.
