At that time the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man coming on the clouds of heaven, with power and great glory.
Textus Receptus (TR) - Matthew 24:30 >Καὶ τότε φανήσεται τὸ σημεῖον τοῦ υἱοῦ τοῦ ἀνθρώπου ἐν τῷ οὐρανῷ· καὶ τότε κόψονται πᾶσαι αἱ φυλαὶ τῆς γῆς, καὶ ὄψονται τὸν υἱὸν τοῦ ἀνθρώπου ἐρχόμενον ἐπὶ τῶν νεφελῶν τοῦ οὐρανοῦ μετὰ δυνάμεως καὶ δόξης πολλῆς.
