[1] = Synagoge 729, Photius epsilon1699; some similar glosses for different forms of the verb can be found at Hesychius espilon5179 and epsilon5181 and epsilon5183. In this particular form (future indicative active, first person singular), the headword is only attested three times outside of lexicography with the sense indicated: Euripides, Alkestis 365 (Web address 1); Lucian, Kataplous 8.12; and Libanius 19.41. Commentary to any of these passages could conceivably be behind this part of the entry, though Libanius is considerably less likely than the other two.
[2] Sophokles, Ajax 566 (Web address 2), where the verb is in the present tense, in contrast to the future tense of the headword and its glosses. A variant of this same passage is quoted at alpha 4211.
