And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. (Matthew 24:30)
See on Dan. 7:13. The expression is found also in Jewish apocalyptic literature. The Book of Enoch (ch. 62:5), for instance, speaks of the time “when they see that Son of Man sitting on the throne of his glory” (cf. Matt. 16:27; 25:31).
Gr. sēmeion, “sign,”“mark,”“token” (see p. 208; see on Luke 2:12). The “token” that will distinguish Christ’s return from the deceptions of the false christs is the cloud of glory with which He returns to this earth (see EW 15, 35; GC 640).
