Luke 11:33-35

American Standard Version

³³ No man, when he hath lighted a lamp, putteth it in a cellar, neither under the bushel, but on the stand, that they which enter in may see the light. ³⁴ The lamp of thy body is thine eye: when thine eye is single, thy whole body also is full of light; but when it is evil, thy body also is full of darkness. ³⁵ Look therefore whether the light that is in thee be not darkness.
