Translation Notes:
"1Ἀλήθειαν λέγω ἐν Χριστῷ, οὐ ψεύδομαι, συμμαρτυρούσης μοι τῆς συνειδήσεώς μου ἐν πνεύματι ἁγίῳ, 2ὅτι λύπη μοί ἐστιν μεγάλη καὶ ἀδιάλειπτος ὀδύνη τῇ καρδίᾳ μου. 3ηὐχόμην γὰρ ἀνάθεμα εἶναι αὐτὸς ἐγὼ ἀπὸ τοῦ Χριστοῦ ὑπὲρ τῶν ἀδελφῶν μου τῶν συγγενῶν μου κατὰ σάρκα, 4οἵτινές εἰσιν Ἰσραηλῖται, ὧν ἡ υἱοθεσία καὶ ἡ δόξα καὶ αἱ διαθῆκαι καὶ ἡ νομοθεσία καὶ ἡ λατρεία καὶ αἱ ἐπαγγελίαι, 5ὧν οἱ πατέρες καὶ ἐξ ὧν ὁ Χριστὸς τὸ κατὰ σάρκα, ὁ ὢν ἐπὶ πάντων θεὸς εὐλογητὸς εἰς τοὺς αἰῶνας, ἀμήν." (Romans 9:1-5 NA27INT).
Translation: 1 I am speaking truth in Christ, I am not lying, while my conscience confirming to me in the Holy Spirit, 2 that grief to me is great and pain in my heart is unceasing. 3 For I could wish myself to be a curse away from Christ in behalf of my brethren, my fellow countrymen according to the flesh, who are Israelites, of whom the adoption and the glory and the covenants and the giving of the law and the service and the promises, 5 of whom the fathers, and from whom the Christ according to the flesh, the one being over all, God blessed unto the ages, amen.
