Mattithyahu (Matthew) 6:22-24

“The lamp of the body is the eye. If therefore your eye is good, all your body shall be enlightened. But if your eye is evil, all your body shall be darkened. If, then, the light that is within you is darkness, how great is that darkness! No one is able to serve two masters, for either he shall hate the one and love the other, or else he shall cleave to the one and despise the other. You are not able to serve Elohim and mammon.
