Ap 7:9-14 (King James)

⁹ After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands; ¹⁰ And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb. ¹¹ And all the angels stood round about the throne, and about the elders and the four beasts, and fell before the throne on their faces, and worshipped God, ¹² Saying, Amen: Blessing, and glory, and wisdom, and thanksgiving, and honour, and power, and might, be unto our God for ever and ever. Amen.
   ¹³ And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they? ¹⁴ And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.

Ap 7:9-14 (Stephanus 1550)

⁹ μετὰ ταῦτα εἶδον καὶ ἰδού ὄχλος πολύς ὃν ἀριθμῆσαι αὐτὸν οὐδεὶς ἠδύνατο ἐκ παντὸς ἔθνους καὶ φυλῶν καὶ λαῶν καὶ γλωσσῶν ἑστῶτες ἐνώπιον τοῦ θρόνου καὶ ἐνώπιον τοῦ ἀρνίου περιβεβλημένοι στολὰς λευκάς καὶ φοίνικες ἐν ταῖς χερσὶν αὐτῶν ¹⁰ καὶ κράζοντες φωνῇ μεγάλῃ λέγοντες ἡ σωτηρία τῷ καθημένῳ ἐπὶ τοῦ θρόνου τοῦ θεοῦ ἡμῶν καὶ τῷ ἀρνίῳ ¹¹ καὶ πάντες οἱ ἄγγελοι ἑστήκεσαν κύκλῳ τοῦ θρόνου καὶ τῶν πρεσβυτέρων καὶ τῶν τεσσάρων ζῴων καὶ ἔπεσον ἐνώπιον τοῦ θρόνου ἐπὶ πρόσωπον αὐτῶν καὶ προσεκύνησαν τῷ θεῷ ¹² λέγοντες ἀμήν ἡ εὐλογία καὶ ἡ δόξα καὶ ἡ σοφία καὶ ἡ εὐχαριστία καὶ ἡ τιμὴ καὶ ἡ δύναμις καὶ ἡ ἰσχὺς τῷ θεῷ ἡμῶν εἰς τοὺς αἰῶνας τῶν αἰώνων ἀμήν ¹³ καὶ ἀπεκρίθη εἷς ἐκ τῶν πρεσβυτέρων λέγων μοι οὗτοι οἱ περιβεβλημένοι τὰς στολὰς τὰς λευκὰς τίνες εἰσὶν καὶ πόθεν ἦλθον ¹⁴ καὶ εἴρηκα αὐτῷ κύριέ σὺ οἶδας καὶ εἶπέν μοι οὗτοί εἰσιν οἱ ἐρχόμενοι ἐκ τῆς θλίψεως τῆς μεγάλης καὶ ἔπλυναν τὰς στολὰς αὐτῶν καὶ ἐλεύκαναν στολὰς αὐτῶν ἐν τῷ αἵματι τοῦ ἀρνίου
