KJV:
But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!
NASB:
"But if your eye is bad, your whole body will be full of darkness. If then the light that is in you is darkness, how great is the darkness!
KJV:
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.
NASB:
"The eye is the lamp of your body; when your eye is clear, your whole body also is full of light; but when it is bad, your body also is full of darkness.
KJV:
If thy whole body therefore be full of light, having no part dark, the whole shall be full of light, as when the bright shining of a candle doth give thee light.
NASB:
"If therefore your whole body is full of light, with no dark part in it, it will be wholly illumined, as when the lamp illumines you with its rays."
