Deuteronomio 7

E non contrarrai matrimonii con loro. Non darai la tua figliuola a un uomo di quella stirpe, né prenderai la figliuola di lui pel tuo figliuolo:

Y no emparentarás con ellos: no darás tu hija á su hijo, ni tomarás á su hija para tu hijo.

Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son.

You shall not make marriages with them. You shall not give your daughter to his son, nor shall you take his daughter for your son.
