Matthew 6:21-23

Young's Literal Translation

²¹ for where your treasure is, there will be also your heart.

²² `The lamp of the body is the eye, if, therefore, thine eye may be perfect, all thy body shall be enlightened,

²³ but if thine eye may be evil, all thy body shall be dark; if, therefore, the light that [is] in thee is darkness -- the darkness, how great!
