Luke 21:9

ἀκαταστασίας, unsettled conditions, for ἀκοὰς πολέμων in Mt. and Mk., and perhaps intended as an explanation of that vague phrase. Hahn refers to the French Revolution and the Socialist movement of the present day as illustrating the meaning. πτοηθῆτε = θροεῖσθε in parallels; here and in Luke 24:37. δεῖ γὰρ, etc., cf. the laconic version in Mk. (W. and H [171]) and notes there. πρῶτον, οὐκ εὐθέως : both emphasising the lesson that the crisis cannot come before certain things happen, and the latter hinting that it will not come even then.

[171] Westcott and Hort.
