And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn (καὶ τότε κόψονται πᾶσαι αἱ φυλαὶ τῆς γῆς), and they shall see the Son of man coming in the clouds of heaven with power and great glory.
-- Matthew 24:30
Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him (καὶ κόψονται ἐπ᾽ αὐτὸν πᾶσαι αἱ φυλαὶ τῆς γῆς). Even so, Amen.
-- Revelation 1:7
