Justin Martyr, The First Apology

And that the Spirit of prophecy might signify to us that He who suffers these things has an ineffable origin, and rules His enemies, He spake thus: “His generation who shall declare? because His life is cut off from the earth: for their transgressions He comes to death. And I will give the wicked for His burial, and the rich for His death; because He did no violence, neither was any deceit in His mouth. And the Lord is pleased to cleanse Him from the stripe. If He be given for sin, your soul shall see His seed prolonged in days. And the Lord is pleased to deliver His soul from grief, to show Him light, and to form Him with knowledge, to justify the righteous who richly serveth many. And He shall bear our iniquities. Therefore He shall inherit many, and He shall divide the spoil of the strong; because His soul was delivered to death: and He was numbered with the transgressors; and He bare the sins of many, and He was delivered up for their transgressions.”105 Isa. liii. 8–12. Hear, too, how He was to ascend into heaven according to prophecy. It was thus spoken: “Lift up the gates of heaven; be ye opened, that the King of glory may come in. Who is this King of glory? The Lord, strong and mighty.”106 Ps. xxiv. 7. And how also He should come again out of heaven with glory, hear what was spoken in reference to this by the prophet Jeremiah.107 This prophecy occurs not in Jeremiah, but in Dan. vii. 13. His words are: “Behold, as the Son of man He cometh in the clouds of heaven, and His angels with Him.”108 Dan. vii. 13.

[51] Ἵνα δὲ μηνύσῃ ἡμῖν τὸ προφητικὸν πνεῦμα ὅτι ὁ ταῦτα πάσχων ἀνεκδιήγητον ἔχει τὸ γένος καὶ βασιλεύει τῶν ἐχθρῶν, ἔφη οὕτως: Τὴν γενεὰν αὐτοῦ τίς διηγήσεται; ὅτι αἴρεται ἀπὸ τῆς γῆς ἡ ζωὴ αὐτοῦ, ἀπὸ τῶν ἀνομιῶν αὐτῶν ἥκει εἰς θάνατον. καὶ δώσω τοὺς πονηροὺς ἀντὶ τῆς ταφῆς αὐτοῦ καὶ τοὺς πλουσίους ἀντὶ τοῦ θανάτου αὐτοῦ, ὅτι ἀνομίαν οὐκ ἐποίησεν οὐδὲ εὑρέθη δόλος ἐν τῷ στόματι αὐτοῦ: καὶ κύριος βούλεται καθαρίσαι αὐτὸν τῆς πληγῆς. ἐὰν δῶτε περὶ ἁμαρτίας, ἡ ψυχὴ ὑμῶν ὄψεται σπέρμα μακρόβιον. καὶ βούλεται κύριος ἀφελεῖν ἀπὸ πόνου τὴν ψυχὴν αὐτοῦ, δεῖξαι αὐτῷ φῶς καὶ πλάσαι τῇ συνέσει, δικαιῶσαι δίκαιον εὖ δουλεύοντα πολλοῖς, καὶ τὰς ἁμαρτίας ἡμῶν αὐτὸς ἀνοίσει. διὰ τοῦτο αὐτὸς κληρονομήσει πολλοὺς καὶ τῶν ἰσχυρῶν μεριεῖ σκύλα, ἀνθ' ὧν παρεδόθη εἰς θάνατον ἡ ψυχὴ αὐτοῦ, καὶ ἐν τοῖς ἀνόμοις ἐλογίσθη, καὶ αὐτὸς ἁμαρτίας πολλῶν ἀνήνεγκε καὶ διὰ τὰς ἀνομίας αὐτῶν αὐτὸς παρεδόθη. ὡς δὲ καὶ εἰς τὸν οὐρανὸν ἔμελλεν ἀνιέναι, καθὼς προεφητεύθη, ἀκούσατε. ἐλέχθη δὲ οὕτως: Ἄρατε πύλας οὐρανῶν, ἀνοίχθητε, ἵνα εἰσέλθῃ ὁ βασιλεὺς τῆς δόξης. τίς ἐστιν οὗτος ὁ βασιλεὺς τῆς δόξης; Κύριος κραταιὸς καὶ κύριος δυνατός. ὡς δὲ καὶ ἐξ οὐρανῶν παραγίνεσθαι μετὰ δόξης μέλλει, ἀκούσατε καὶ τῶν εἰρημένων εἰς τοῦτο διὰ Ἰερεμίου τοῦ προφήτου. ἔστι δὲ ταῦτα: Ἰδοὺ ὡς υἱὸς ἀνθρώπου ἔρχεται ἐπάνω τῶν νεφελῶν τοῦ οὐρανοῦ, καὶ οἱ ἄγγελοι αὐτοῦ σὺν αὐτῷ.
