The Odyssey 20.227–234
Now be my witness Zeus above all gods, and this hospitable board, and the hearth of noble Odysseus to which I am come, that verily while thou art here Odysseus shall come home, and thou shalt see with thine eyes, if thou wilt, the slaying of the wooers, who lord it here.”
βουκόλʼ, ἐπεὶ οὔτε κακῷ οὔτʼ ἄφρονι φωτὶ ἔοικας,
γιγνώσκω δὲ καὶ αὐτὸς ὅ τοι πινυτὴ φρένας ἵκει,
τοὔνεκά τοι ἐρέω καὶ ἐπὶ μέγαν ὅρκον ὀμοῦμαι·
ἴστω νῦν Ζεὺς πρῶτα θεῶν ξενίη τε τράπεζα
ἱστίη τʼ Ὀδυσῆος ἀμύμονος, ἣν ἀφικάνω,
ἦ σέθεν ἐνθάδʼ ἐόντος ἐλεύσεται οἴκαδʼ Ὀδυσσεύς·
σοῖσιν δʼ ὀφθαλμοῖσιν ἐπόψεαι, αἴ κʼ ἐθέλῃσθα,
κτεινομένους μνηστῆρας, οἳ ἐνθάδε κοιρανέουσιν.
