Lexicon :: Strong's G1491 - eidos

εἶδος, -ους, τό, (ΕΙΔΩ), in the Sept. chiefly for מַרְאֶה and תֹּאַר; properly, that which strikes the eye, which is exposed to view;
1. the external appearance, form, figure, shape, (so from Homer down): John 5:37; σωματικῷ εἴδει, Luke 3:22; τὸ εἶδος τοῦ προσώπου αὐτοῦ, Luke 9:29; διὰ εἴδους, as encompassed with the visible appearance (of eternal things), (see διά, A. I. 2), 2 Corinthians 5:7, — commonly explained, by sight i. e. beholding (Luth.: im Schauen); but no example has yet been adduced from any Greek writings in which εἶδος is used actively, like the Latin species, of vision; (στόμα κατὰ στόμα, ἐν εἴδει, καὶ οὐ δἰ ὁραμάτων καὶ ἐνυπνίων, Clement. homil. 17, 18; cf. Numbers 12:8 Sept.).
2. form, kind: ἀπὸ παντὸς εἴδους πονηροῦ ἀπέχεσθε, i. e. from every kind of evil or wrong, 1 Thessalonians 5:22 [cf.πονηρός, under the end]; (Josephus, Antiquities 10, 3, 1 πᾶν εἶδος πονηρίας. The Greeks, especially Plato, oppose τὸ εἶδος to τὸ γένος, as the Latin does species to genus. Cf. Schmidt, chapter 182, 2).
