Eye - Vine's Expository Dictionary of New Testament Words
Eye[ 1,,G3788, ophthalmos ]
akin to opsis, sight," probably from a root signifying "penetration, sharpness" (Curtius, Gk. Etym.) (cp. Eng., "ophthalmia," etc.). is used
(a) of the physical organ, e.g., Matthew 5:38; of restoring sight, e.g., Matthew 20:33; of God's power of vision, Hebrews 4:13; 1 Peter 3:12; of Christ in vision, Revelation 1:14; Revelation 2:18; Revelation 19:12; of the Holy Spirit in the unity of Godhood with Christ, Revelation 5:6;
(b) metaphorically, of ethical qualities, evil, Matthew 6:23; Mark 7:22 (by metonymy, for envy); singleness of motive, Matthew 6:22; Luke 11:34; as the instrument of evil desire, "the principal avenue of temptation," 1 John 2:16; of adultery, 2 Peter 2:14;
(c) metaphorically, of mental vision, Matthew 13:15; John 12:40; Romans 11:8; Galatians 3:1, where the metaphor of the "evil eye" is altered to a different sense from that of bewitching (the posting up or placarding of an "eye" was used as a charm, to prevent mischief); by Gospel-preaching Christ had been, so to speak, placarded before their "eyes;" the question may be paraphrased, "What evil teachers have been malignly fascinating you?;" Ephesians 1:18, of the "eyes of the heart," as a means of knowledge.
[ 2,,G3659, omma ]
"sight," is used in the plural in Matthew 20:34 (No. 1 is used in Matthew 20:33); Mark 8:23 (No. 1 is used in Mark 8:25). The word is more poetical in usage than No. 1, and the writers may have changed the word with a view to distinguishing the simple desire of the blind man from the tender act of the Lord Himself.
[ 3,,G5168, trumalia ]
is used of the "eye" of a needle, Mark 10:25 (from trume, "a hole," truo, "to wear away"). Cp. trema, "a hole, perforation," Matthew 19:24 (some texts have trupema, "a hole," from trupao, "to bore a hole"); Luke 18:25, as in the most authentic mss. (some texts have trumalia here).
