μέντοι (μέν, τοι) (Tr μέν τοι in 2Ti_2:19), a particle of affirmation, and hence, also often of opposition (on its various use in classical Greek cf. Devar., p. 124f and Klotz's comments, vol. ii. 2, pp. 60 and 663ff; Herm. ad Vig., p. 840f), but yet, nevertheless, howbeit: Joh_4:27; Joh_7:13; Joh_20:5; Joh_21:4; 2Ti_2:19; Jud_1:8 (the connection of which verse with what precedes is as follows: 'although these examples were set forth as warnings, nevertheless' etc.); ὅμως μέντοι, yet nevertheless, Joh_12:42; μέντοι, equivalent to rather, Jas_2:8 (if ye do not have respect of persons, but rather observe the law of love, with which προσωποληψία is incompatible; (if however, howbeit if)).

μέντοι [page 397]
For this particle of affirmation, which was originally a strengthened μέν , cf. P Tebt II. 411 .12 (ii/A.D.) μηδὲν μέντοι θορυβηθῇς , do not be disturbed however, P Giss I. 47 .21 (time of Hadrian) (= Chrest. I. p. 383 ) ἃς μέντοι δεδώκεις εἰς το̣ῦτο̣ (δραχμὰς ) κ̄δ̄ ἔπεμψᾶ σοι , P Oxy XII. 1420 .8 ( c. A.D. 129) ἀλλ [ὰ ] μέντοι καὶ τὸ [ν ] Ἀγαθεῖνον συν [κατα ]χω [ρίσ ]α̣ι̣ δ̣ε̣ι̣ͅ , Agathinus too, however, must join in presenting them certain accounts, and P Ryl II. 75 .8 (late ii/A.D.) μέντοι τύπος ἐστὶν καθ᾽ ὃν ἔκρεινα πολλάκις , only there is a principle according to which I have often judged (Edd.). Μέντοι stands first in the sentence (see s.v. μενοῦνγε ) in P Lond 1711 .84 (A.D. 566 573) μέντοι καὶ αὐτῆς τῆς σῆς κοσμιότητος ὑπακούσῃς μοι κτλ . Wackernagel ( Hellenistica , p. 11) draws attention to the Doric form μέντον for μέντοι in P Hib I. 40 .7 (B.C. 261) ἐπίστασο μέντον ἀκριβῶς , but you must clearly understand, as against the editors note that the writer was capable of mistakes. The adversative force of the particle appears in such passages from the NT as Joh_4:27 ; Joh_7:13 , al. : cf. also Jas_2:8 , where, however, Hort thinks that μέντοι retains its original force of a strong affirmation, and translates indeed, really : cf. Kόhner-Gerth § 503, 3, g.
