Acts 2
25 Δαυὶδ γὰρ λέγει εἰς αὐτόν· Προορώμην τὸν κύριον ἐνώπιόν μου διὰ παντός, ὅτι ἐκ δεξιῶν μού ἐστιν ἵνα μὴ σαλευθῶ.
26 διὰ τοῦτο ηὐφράνθη ἡ καρδία μου καὶ ἠγαλλιάσατο ἡ γλῶσσά μου, ἔτι δὲ καὶ ἡ σάρξ μου κατασκηνώσει ἐπ’ ἐλπίδι·
27 ὅτι οὐκ ἐγκαταλείψεις τὴν ψυχήν μου εἰς ᾅδην, οὐδὲ δώσεις τὸν ὅσιόν σου ἰδεῖν διαφθοράν.
28 ἐγνώρισάς μοι ὁδοὺς ζωῆς, πληρώσεις με εὐφροσύνης μετὰ τοῦ προσώπου σου.
29 Ἄνδρες ἀδελφοί, ἐξὸν εἰπεῖν μετὰ παρρησίας πρὸς ὑμᾶς περὶ τοῦ πατριάρχου Δαυὶδ, ὅτι καὶ ἐτελεύτησεν καὶ ἐτάφη, καὶ τὸ μνῆμα αὐτοῦ ἔστιν ἐν ἡμῖν ἄχρι τῆς ἡμέρας ταύτης·
