This entry appears twice: here (out of alphabetical order) and again at pi 649. See also, according to Adler, the unpublished Ambrosian Lexicon (264).
The headword (perhaps, though not necessarily, extracted from the quotation that follows) is first person singular of the verb pari/hmi, literally I drop alongside (but with a range of other senses); see LSJ s.v. and pi 575.
[1] The gloss is first person singular of the verb sungxw/rw, see LSJ. s.v., sigma 1311, pi 714 (end).
[2] This 'of us' was unnecessarily emended to 'of you' in the editio princeps.
[3] As Adler notes, Toup replaced e)pelqw/n with ei)selqei=n; Kuster simply deemed the passage corrupt.
[4] Quotation unidentifiable (but seemingly from a speech by a general or other military commander, asserting that his encampment--even within foreign territory--is sacrosanct).
