Matthew 24:9

θλίψιν. Rare in the classics, the figurative sense is late in the noun but appears in the verb, Aristoph. Vespæ 1289 and elsewhere. In Philippians 1:17 the literal ‘pressure’ of the chain is thought of: θλίψιν ἐγείρειν, ‘to make my chain gall me’ (Bp. Lightfoot). θλίψις is preferable to θλίψις, though the latter is the Attic accentuation. The tendency of later Greek was to shorten the penultimate. See Winer, pp. 56, 57 and Dr Moulton’s note.
