Matthew 5:28-32

but I say to you that everyone who looks at a woman with lust for her has already committed adultery with her in his heart.

Now if your right eye is causing you to sin, tear it out and throw it away from you; for it is better for you to lose one of the parts of your body, than for your whole body to be thrown into hell.

And if your right hand is causing you to sin, cut it off and throw it away from you; for it is better for you to lose one of the parts of your body, than for your whole body to go into hell.

“Now it was said, ‘Whoever sends his wife away is to give her a certificate of divorce’;

but I say to you that everyone who divorces his wife, except for the reason of sexual immorality, makes her commit adultery; and whoever marries a divorced woman commits adultery.
