Proverbs 6:31-33

New Revised Standard Version, Anglicised

³¹ Yet if they are caught, they will pay sevenfold;
    they will forfeit all the goods of their house.
³² But he who commits adultery has no sense;
    he who does it destroys himself.
³³ He will get wounds and dishonour,
    and his disgrace will not be wiped away.
