Luke 11:36

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.

35 Take heed therefore that the light which is in thee be not darkness.

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.

37 And as he spake, a certain Pharisee besought him to dine with him: and he went in, and sat down to meat.

38 And when the Pharisee saw it, he marvelled that he had not first washed before dinner.

Do read the surrounding verses too, because the context often says more than a single verse.
