Paul remained in Corinth for quite some time before saying goodbye to the brothers. He had his head shaved in Cenchrea to keep a vow he had made, and then he sailed for Syria, accompanied by Priscilla and Aquila.
Textus Receptus (TR) - Acts 18:18 >Ὁ δὲ Παῦλος ἔτι προσμείνας ἡμέρας ἱκανάς, τοῖς ἀδελφοῖς ἀποταξάμενος, ἐξέπλει εἰς τὴν Συρίαν, καὶ σὺν αὐτῷ Πρίσκιλλα καὶ Ἀκύλας, κειράμενος τὴν κεφαλὴν ἐν Κεγχρεαῖς· εἶχε γὰρ εὐχήν.
