The nakedness of thy son’s daughter, or of thy daughter’s daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.

You may not have sex relations with your son's daughter or your daughter's daughter, for they are part of yourself;

Ασχημοσυνην θυγατρος του υιου σου η θυγατρος της θυγατρος σου, τουτων την ασχημοσυνην δεν θελεις αποκαλυψει διοτι ιδικη σου ειναι η ασχημοσυνη αυτων.
