Luke 11:34-36

RYLT(i) 34 'The lamp of the body is the eye, when then your eye may be simple, your whole body also is lightened; and when it may be evil, your body also is darkened; 35 take heed, then, lest the light that is in you be darkness; 36 if then your whole body is lightened, not having any part darkened, the whole shall be lightened, as when the lamp by the brightness may give you light.'
