Matthew 6:19-24 (King James Version)
19Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
20But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
21For where your treasure is, there will your heart be also.
22The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.
23But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!
24No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
