17 τοῦτο οὖν βουλόμενος μήτι ἄρα τῇ ἐλαφρίᾳ ἐχρησάμην; ἢ ἃ βουλεύομαι, κατὰ σάρκα βουλεύομαι, ἵνα ᾖ παρ᾿ ἐμοὶ τὸ ναὶ ναὶ καὶ τὸ οὒ οὔ;
18 πιστὸς δὲ ὁ Θεὸς ὅτι ὁ λόγος ἡμῶν ὁ πρὸς ὑμᾶς οὐκ ἐγένετο ναὶ καὶ οὔ.
19 ὁ γὰρ τοῦ Θεοῦ υἱὸς ᾿Ιησοῦς Χριστὸς ὁ ἐν ὑμῖν δι᾿ ἡμῶν κηρυχθείς, δι᾿ ἐμοῦ καὶ Σιλουανοῦ καὶ Τιμοθέου, οὐκ ἐγένετο ναὶ καὶ οὔ, ἀλλὰ ναὶ ἐν αὐτῷ γέγονεν·
20 ὅσαι γὰρ ἐπαγγελίαι Θεοῦ, ἐν αὐτῷ τὸ ναὶ καὶ ἐν αὐτῷ τὸ ἀμήν, τῷ Θεῷ πρὸς δόξαν δι᾿ ἡμῶν.
21 ὁ δὲ βεβαιῶν ἡμᾶς σὺν ὑμῖν εἰς Χριστὸν καὶ χρίσας ἡμᾶς Θεός,
22 ὁ καὶ σφραγισάμενος ἡμᾶς καὶ δοὺς τὸν ἀρραβῶνα τοῦ Πνεύματος ἐν ταῖς καρδίαις ἡμῶν.
23 ᾿Εγὼ δὲ μάρτυρα τὸν Θεὸν ἐπικαλοῦμαι ἐπὶ τὴν ἐμὴν ψυχήν, ὅτι φειδόμενος ὑμῶν οὐκέτι ἦλθον εἰς Κόρινθον.
