Νῆστις
From LSJ
μή μοι θεοὺς καλοῦσα βουλεύου κακῶς· πειθαρχία γάρ ἐστι τῆς εὐπραξίας μήτηρ, γυνὴ Σωτῆρος· ὦδ᾽ ἔχει λόγος → When you invoke the gods, do not be ill-advised. For Obedience is the mother of Success, wife of Salvation—as the saying goes.

Etymology: Aetius 1, 3, 20 gives the definition κρούνωμα βρότειον. DELG thinks that Bollack did not prove a relation with νῆστις. Cf. Mayer, Mél. Boisacq 2, 135. Krahe, Spr. der Illyrier 1, 85 supposes *ned-ti-, comaring the group Νεδα. Cf. Perpillou, 1972, 113f.
