"I made a covenant with my eyes not to look with lust upon a girl. I know full well that the Almighty God sends calamity on those who do" (Job 31:1-3, The Living Bible).

"You have heard that it was said, 'Do not commit adultery.' But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart" (Matthew 5:28).

Fair play!
