Moulton & Milligan — Vocabulary of the Greek NT
ὄλεθρος. For a somewhat weakened use of this strong word, which in Biblical usage implies ‘‘ ruin,” the loss of all that gives worth to existence (see Milligan ad 1 Thess 5°), cf. BGU IV. 1027 **¥i.1 (iv/a.p.) (as amended Crest. I. p. sor) ἐν ὁποίῳ κιντύνῳ καθεστήκατε, οἵου ὀλέθρου πιρασ[θ]ήσεσθαι οὐκ αὐτοὶ μόνοι, ἀλλὰ καὶ ὁϊλ]όκληρον ὑμῶν τὸ βουλευτήριον--ἃ representation of the great danger that was being incurred at Hermopolis by the withholding of their avnona from the soldiers for three years. Like Lat. pernzcizes (Ter. Ad. 188), ὄλεθρος is used as a comic hyperbole applied to a person (‘‘pest’’). For a new ex. see Menander Samza 133 χαμαιτύπη δ᾽ ἄνθρωπος, ὄλεθρος. The ordinary force of ὄλεθρος is seen in Sy// 463 (-Ξ 527)8? (c. B.C. 220) κακίστῳ ὀλέθρωι ἐξόλλυσθαι. For exx. of the adj. ὀλέθριος, which is read by Lachmann in 2 Thess 1°, see Cronert Mem. Herc. p. 186.
