23.129 · Physiological Processes and States · Health, Vigor, Strength
to be well, to be healthy the state of being healthy, well (in contrast with sickness) In a number of languages health is expressed only in terms of strength, for ‘to be well’ is ‘to be strong.’ In other languages, however, to be well or to be healthy is a negation of illness or sickness, so that in MRK 16:18 one may translate ‘they will place their hands on those who are sick and these people will become not sick.’

ὑγιαίνω, “κἀπὶ in good health,’’ is very com:mon in private letters, e.g. (a) at the opening—BGU II. 4233 (ii/A.D.) (= Se/ectzons, p- 90) πρὸ μὲν πάντων εὔχομαί σε ὑγιαίνειν, or (Ὁ) at the close—P Oxy IV. γ45}0 (c. A.D. 1) ἀ[σ]πάζου πάντας τοὺς σοὺς καὶ σεαυτοῦ ἐπιμέλου ἵν᾽ ὑγιαίνῃς : cf. Herodas VI. 97 ὑγίαινε, ‘‘good-bye” or ‘‘ good-night,” with Headlam’s note. For a metaph. usage, as in the Pastorals (1 Tim 11° a/.), cf. P Oxy II. 291° (A.D. 25-26) προέγραψ[ά σοι] ἀνδραγαθι[ν] καὶ ἀπαιτεῖν plex pt ὑγια[Π νων παρ[α]γένωμαι, “1 have already written to you to be firm and demand payment
