Matthew 6:19-23

19Lay not up for yourselves treasures upon the earth, where moth and rust spoils, and where thieves dig through and steal;

20but lay up for yourselves treasures in heaven, where neither moth nor rust spoils, and where thieves do not dig through nor steal;

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

22The lamp of the body is the eye; if therefore thine eye be single, thy whole body will be light:

23but if thine eye be wicked, thy whole body will be dark. If therefore the light that is in thee be darkness, how great the darkness!
