You have heard it declared ‘You shall not  commit adultery.’

But I say to you that every man
who looks at a woman
to desire her
already has committed adultery with her in his heart. 

If your right eye causes you to stumble,
pull it out and throw it away from you. 
For it is better for you to lose one part of your body
than your whole body be thrown in to Gehenna,

And if your right hand causes you to stumble,
cut it off and throw it away from you. 
For it is better for you to lose one part of your body
than your whole body go to Gehenna. 

Be thou my vision, O Lord of my heart;
Naught be all else to me, save that thou art –
Thou my best thought, by day or by night;
Waking or sleeping, thy presence my light.
