Acts 3
1 Πέτρος δὲ καὶ Ἰωάννης ἀνέβαινον εἰς τὸ ἱερὸν ἐπὶ τὴν ὥραν τῆς προσευχῆς τὴν ἐνάτην,
2 καί τις ἀνὴρ χωλὸς ἐκ κοιλίας μητρὸς αὐτοῦ ὑπάρχων ἐβαστάζετο, ὃν ἐτίθουν καθ’ ἡμέραν πρὸς τὴν θύραν τοῦ ἱεροῦ τὴν λεγομένην Ὡραίαν τοῦ αἰτεῖν ἐλεημοσύνην παρὰ τῶν εἰσπορευομένων εἰς τὸ ἱερόν,
3 ὃς ἰδὼν Πέτρον καὶ Ἰωάννην μέλλοντας εἰσιέναι εἰς τὸ ἱερὸν ἠρώτα ἐλεημοσύνην λαβεῖν.
4 ἀτενίσας δὲ Πέτρος εἰς αὐτὸν σὺν τῷ Ἰωάννῃ εἶπεν· Βλέψον εἰς ἡμᾶς.
5 ὁ δὲ ἐπεῖχεν αὐτοῖς προσδοκῶν τι παρ’ αὐτῶν λαβεῖν.
