Matthew 6:21

Don't lay up treasures for yourselves on the earth, where moth and rust consume, and where thieves break through and steal;

but lay up for yourselves treasures in heaven, where neither moth nor rust consume, and where thieves don't break through and steal;

The lamp of the body is the eye. If therefore your eye is sound, your whole body will be full of light.

But if your eye is evil, your whole body will be full of darkness. If therefore the light that is in you is darkness, how great is the darkness!
