Luke 11:34-36

Worsley(i) 34 The eye is the candle of the body: therefore when thine eye is clear, thy whole body also is light; but when it is bad, thy body also is dark. 35 Take heed therefore least the light which is in thee be darkness. 36 For if thy whole body be light, having no part dark, it will be (when all enlightened) as when a candle giveth thee light by its brightness.
