Proverbs 6:29-33

So is he who goes in to his neighbor’s wife; none who touches her will go unpunished. People do not despise a thief if he steals to satisfy his appetite when he is hungry, but if he is caught, he will pay sevenfold; he will give all the goods of his house. He who commits adultery lacks sense; he who does it destroys himself. He will get wounds and dishonor, and his disgrace will not be wiped away.
