= Synagoge epsilon643; Photius, Lexicon epsilon1483; and, with a slightly different gloss (xare/ntes), already Hesychius epsilon4596.
The headword is aorist passive participle, masculine nominative plural, of e)ph/domai, apparently a variant of e)fh/domai exhibiting psilosis characteristic of certain Greek dialects, most notably Ionic. Other psilotic forms of the same verb appear with analogous glosses in Hesychius epsilon4595 (aorist passive optative, third person plural) and Lexica Segueriana (Bekker) 228.26 (aorist passive participle masculine/neuter genitive singular). But the only attestation of any form outside lexicography comes from the fourth century CE, in a fragment of the Neoplatonic philosopher Eusebius of Myndus (fr. 1 Mullach) quoted by Stobaeus (3.1.103); it has the aorist passive optative, first person singular. To judge by his fragments Eusebius wrote in a literary Ionic unusual for his period, so it is quite possible that the present headword as well as the other psilotic forms similarly glossed in other lexica come from his writings.
