The Odyssey 18.52–57
But come now, do you all swear to me a mighty oath, to the end that no man, doing a favour to Irus, may deal me a foul blow with heavy hand, and so by violence subdue me to this fellow.”
So he spoke, and they all gave the oath not to smite him, even as he bade. But when they had sworn and made an end of the oath,
ὦ φίλοι, οὔ πως ἔστι νεωτέρῳ ἀνδρὶ μάχεσθαι
ἄνδρα γέροντα, δύῃ ἀρημένον· ἀλλά με γαστὴρ
ὀτρύνει κακοεργός, ἵνα πληγῇσι δαμείω.
ἀλλʼ ἄγε νῦν μοι πάντες ὀμόσσατε καρτερὸν ὅρκον,
μή τις ἐπʼ Ἴρῳ ἦρα φέρων ἐμὲ χειρὶ βαρείῃ
πλήξῃ ἀτασθάλλων, τούτῳ δέ με ἶφι δαμάσσῃ.
