Matthew 6:19-22

19. Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
20. But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
21. For where your treasure is, there will your heart be also.
22. The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.
