Euripides, Iphigenia at Aulis 1211-15 = Orph. 948 Bernabé

How to quote this translation

εἰ μὲν τὸν Ὀρφέως εἶχον, ὦ πάτερ, λόγον,
πείθειν ἐπάιδουσ’, ὥσθ’ ὁμαρτεῖν μοι πέτρας
κηλεῖν τε τοῖς λόγοισιν οὓς ἐβουλόμην,
ἐνταῦθ’ ἂν ἦλθον· νῦν δέ, τἀπ’ ἐμοῦ σοφά,
δάκρυα παρέξω·

If I had the speech of Orpheus, father, so as to persuade by incantation, so that rocks followed me and I bewitched anyone I wished with my words, I would have used it. But as it is, I will provide what sophistries I have: my tears.
