2 Corinthiens 1:18-20

18πιστὸς δὲ ὁ Θεὸς, ὅτι ὁ λόγος ἡμῶν ὁ πρὸς ὑμᾶς οὐκ ἐγένετο ναὶ καὶ οὔ.

19ὁ γὰρ τοῦ Θεοῦ υἱὸς Ἰησοῦς Χριστὸς ὁ ἐν ὑμῖν δι’ ἡμῶν κηρυχθείς, δι’ ἐμοῦ καὶ Σιλουανοῦ καὶ Τιμοθέου, οὐκ ἐγένετο ναὶ καὶ οὔ, ἀλλὰ ναὶ ἐν αὐτῷ γέγονεν.

20ὅσαι γὰρ ἐπαγγελίαι Θεοῦ, ἐν αὐτῷ τὸ ναί, καὶ ἐν αὐτῷ τὸ ἀμὴν, τῷ Θεῷ πρὸς δόξαν δι’ ἡμῶν.
