Matthew 6:22-24 The eye is the lamp of the body. So if your eye is clear, your whole body will be full of light.

BLB⁽ⁱ⁾ ²² The eye is the lamp of the body. So if your eye is clear, your whole body will be full of light. ²³ But if your eye is evil, your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness! ²⁴ No one is able to serve two masters, for either he will hate the one and he will love the other, or he will be devoted to the one and he will despise the other. You are not able to serve God and mammon.
