39.34 · Hostility, Strife · Rebellion
to rebel against, to revolt, to engage in insurrection, rebellion to rise up in open defiance of authority, with the presumed intention to overthrow it or to act in complete opposition to its demands It is possible that ἀκαταστασία in LUK 21:9 denotes merely unsettled conditions, but it is far more likely to carry the meaning of ‘insurrections’ and ‘revolts.’
1 ἀκαταστασία[b] differs from ἀκαταστασία[a] ‘revolt, rebellion’ (39.34) in that the violent opposition is directed against some person or local circumstance, rather than against governmental authority.

Moulton & Milligan — Vocabulary of the Greek NT
ἀκαταστασία. A literary citation for this Stoic word may be made from P Grenf I. 14 (ii/B.c.), the Erotic fragment, where the faithless lover is called ἀκαταστασίης εὑρέτης. See also the astrolegical papyrus published in Archiv i. p. 493 f. τῆς συ[μβ]ίου σῆς ἀκαταστασί[αν] (1. 25 f.). It occurs nearly a dozen times in Vettius Valens, coupled with πλάνη καὶ ἀλητεία (p. 418), ἀνωμαλία (p. 4418—one MS.), στάσις, ἔχθρα, συνοχή, κρίσις, ταραχή, etc.: it several times has οἰκείων dependent on it. The verb ἀκαταστατέω also occurs three times. That the astrologers had so thoroughly domesticated it does not prove that Paul, James and Luke were using a word of the higher culture.
