ῤώννυμι: to make strong, to strengthen; perfect passive ἔρρωμαι (see Rho), to be strong, to thrive, prosper; hence, the 2 person (singular) imperative is the usual formula in closing a letter, ἔρρωσο, farewell: Act_23:30 (R G); ἔρρωσθε, Act_15:29 (2Ma_11:21; Xenophon, Cyril 4, 5, 33; Artemidorus Daldianus, oneir. 3, 44, others; ἔρρωσο καί ὑγίαινε, Dio Cassius, 61, 13). STRONGS NT 4517a: σ [σ ,Sigma: the practice (adopted by Griesbach, Knapp, others, after H. Stephanus, et al.) of employing the character sigma σ in the middle of a compound word has been abandoned by the recent critical editors; cf. Winers Grammar, § 5, the passage cited; Lipsius, Gram. Untersuch., p. 122; Matthiae, § 1 Anm. 5; Alexander Buttmann (1873) Ausf. Sprchl. § 2 Anm. 3; Kühner, § 1 Anm. 1. Tdf. edition 8 writes sigma ς' also even at the end of a word, after the older manuscripts. On movable final sigma ς' see ἀχρἱσ', μεχρἱσ', ὁυτὡσ'. The (Ionic) combinations ῥς for ῥρ, and σς for ττ (cf. Fischer, Animadvers. ad Veller. etc. i., pp. 193f, 203; Kühner, § 31, pp. 124, 127), have become predominant (cf. ἄρσην, θαρσέω, θάρσος, ἀπαλλάσσω etc., γλῶσσα, ἥσσων (which see), θάλασσα, κηρύσσω, περισσός, πράσσω (which see), τάσσω, τέσσαρες, φυλάσσω, etc.), except in a few words, as κρείττων (which see), the derivatives of ἐλαττῶν (of which word both forms are used indiscriminately), ἥττημα, ἡττάω (yet see 2Co_12:13), etc.; cf. Buttmann, 7. Some proper names are spelled indifferently with one sigma ς' or with two; as, Ἐλισ῾σ᾿αιος. Zeta ζ' is occasionally substituted for sigma ς', especially before mu μ', see σβέννυμι, Σμύρνα (σμύρνα, cf. Sophocles Glossary, § 58, 3, and Lexicon, under the word; Tdf. Proleg., p. 80; WHs Appendix, p. 148; Buttmann, 5; Alexander Buttmann (1873) Ausf. Sprchl. § 3 Anm. 6; Bezae manuscript, Scrivener edition, p. xlviii.; Liddell and Scott, under the word Zeta ζ', I. 3, and Sigma ς', II. 14 c.); so also xi Ξ, as ξυμβαίνω 1Pe_4:12 Rbez cf. Kühner, § 325, 5; Alexander Buttmann (1873) Ausf. Spr. as above; see ξύν.]

ῥώννυμι [page 566] Ἔρρωσο , ἔρρωσθε ( uale, ualete ), are regular closing formulae (as in Act_15:29 ) in both private and official letters. Naturally they are much varied by the addition of terms of endearment and otherwise, particularly during the second and third centuries A.D. The following exx. must suffice : P Tebt II. 315 .36 (ii/A.D.) ἔρρωσό μοι , τιμιώτατε , P Hamb I. 54 ii. 15 (ii/iii A.D.) ἔρρωσό μοι πολλοῖς χρόνοις ὑγια̣ι̣νων μετὰ καὶ τῶν σῶν , P Oxy XII. 1586 .15 (early iii/A.D.) ἐρρῶσθ (αι ) εὔχομ (αι ) [π ]ανοικεί , ib . I.122 .12 (iii/iv A.D.) ἐρ ]ρῶσθαί σε , κύριέ μου ἄδελφε , πολλοῖς χρόνοις καὶ προκόπτειν εὔχομαι . Many other exx. will be found in Exler Epistolography p. 74 ff. For the verb = have strength of persons cf. PSI V. 495 .22 ( B. C . 258 7) βουλόμεθα γάρ σε τῶι τε σώματι ἐρρῶσθ [αι , and of trees cf. CP Herm I. 28 .11 φοίνικες ἄλλοι ἐρ [ρω ]μένοι . The subst. ῥῶσις is used in connexion wilh praying for strength for anyone, e.g. OGIS 206 .4 εὐξάμενος ῥῶσιν καὶ τέκνοις καὶ γαμετῇ . See also in application to the body Vett. Val. p. 160 .13 . [Supplemental from 1930 edition] Add the unusual formula P Oxy XVII. 2107 .9 (A.D. 262) ἐρρῶσθαι ὑμᾶς εἴη , I hope for your health.
