Luke 11:34

The light of the body is the eye Rather, The eye is the candle of the body, since the word is the same as in the last verse.

therefore when thine eye is single The eye in this clause is the -inward eye" of conscience; the -illuminated eye of the heart," Ephesians 1:17-18. -Single," i.e. unsophisticated; in its normal condition.

when thine eye is evil The -evil eye" is especially one of hate,Romans 12:8; Sir 14:8-10. The inward eye should be spiritual;when it becomes carnal the man can no longer see that which is only spiritually discerned, and he takes God's wisdom for foolishness, 1 Corinthians 2:14; 1 Corinthians 3:18-20.
