Luke 11:34 The light of the body is the eye: therefore when thine eye is single, thy whole body also is full of light; but when thine eye is evil, thy body also is full of darkness.
Revelation 3:18 ...and anoint thine eyes with eyesalve, that thou mayest see.[no vision, they don't see they are being lukewarm]
Isaiah 28:7 ...they err in vision, they stumble in judgment.
[vision and eye in these verses seems to be parallel to exercising righteous judgment, as if, godly perception unclouded by lies]
