[1] The headword (presumably extracted from the quotation given) is future indicative active, third person singular, of the rare verb e)pirre/zw (here in sense 2 distinguished by LSJ s.v.). Hesychius epsilon5103 glosses its aorist active infinitive with e)piqu=sai.
[2] Greek Anthology 6.157.3-4 (Theodoridas); cf. nu 458. On this epigram, a prayer and vow to Artemis, see Gow and Page vol. I (191-192), vol. II (539-540), and further extracts at kappa 1838 and sigma 95. In his prayer, Gorgos entreats the goddess to provide endless protection of his property from thieves (cf. kappa 1838 note); as Gow and Page note (vol. II, 540), this context makes the second interpretation of the headword ("besides") a bit more reasonable.
