(20:5) "You shall not bow down to them and you shall not serve them." What is the intent of this? From (Devarim 17:3) "… and he go and serve other gods and he bow down to them," I would not know whether he is liable for the serving in itself and for the bowing down in itself or that he is not liable until he serves and bows down; it is, therefore, written (here) "You shall not bow down to them and you shall not serve them" — to make each liable in itself.
