The headword phrase is presumably a quotation but is nowhere attested before the Suda. (There is a solitary post-Suda instance, in Maximus Planudes' [C13] Greek version of Ovid's Metamorphoses 10.304.) In any event, it uses the possessive adjective e)mai/, a classical form, which is glossed by the genitive pronoun mou, more commonly used in later Greek.
cf. epsilon 967.
