μυέω, μύω: perfect passive μεμύημαι; (from μύω to close, shut ((cf. Latinmutus); Curtius, § 478));

a. to initiate into the mysteries (Herodotus, Aristophanes, Plato, Plutarch, others; 3Ma 2:30).

b. universally, "to teach fully, instruct; to accustom one to a thing; to give one an intimate acquaintance with a thing": ἐν παντί καί ἐν πᾶσι μεμύημαι, to every condition and to all the several circumstances of life have I become accustomed; I have been so disciplined by experience that whatsoever be my lot I can endure, Php 4:12; (but others, instead of connecting ἐν παντί etc. here (as object) with μεμύημαι (a construction apparently without precedent; yet cf. Lünemann in Winer’s Grammar, § 28, 1) and taking the infinitives that follow as explanatory of the ἐν παντί etc., regard the latter phrase as stating the sphere (see πᾶς, II. 2 a.) and the infinitives as epexegetic (Winers Grammar, § 44, 1): in everything and in all things have I learned the secret both to be filled etc.).
