Matthew 6:23
King James Version
“But 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 that darkness!”
Context
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 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.
25Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
26Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?
