BDAG tells me:
ἐριθεία, ας, ἡ (W-H. ἐριθία; s. Mlt-H. 339): found before NT times only in Aristot., Polit. 5, 3 p. 1302b, 4; 1303a, 14, where it denotes a self-seeking pursuit of political office by unfair means.
It would be a big job to do it.
But.
Wouldn't it be amazing if I could click on those references to extra biblical texts and be taken to them if they are in my library? To the pinpointed location suggested by BDAG?
