2 Corinthians 10:6
Being in readiness (en etoimw exontev). This very idiom occurs in Polybius, Philo, etc. "Holding in readiness." In II Corinthians 12:14 we have etoimwv exw for the same idea (adverb etoimwv).
Disobedience (parakohn). Rare word (Plato, papyri) hearing amiss (aside), failing to hear, refusing to heed (cf. Matthew 18:17 for same idea in parakouw). In N.T. only here; Romans 5:19; Hebrews 2:2. In contrast with upakoh (obedience) rather than the common apeiqia (Romans 11:30, Romans 11:32).
When your obedience shall be fulfilled (otan plhrwqh umwn h upakoh). Indefinite temporal clause with otan and first aorist passive subjunctive. Paul expects that the whole church will become obedient to Christ's will soon as came true.
