רב יוסף was sitting and contemplating it - יתיב רב יוסף וקא מעיין בה
Summary:
One may accept money from an עכו"ם to distribute for צדקה (to עכו"ם) if it is for שלום מלכות. One may even distribute it for ישראל if otherwise it would be גניבת דעת . Donations to a ביכנ"ס may be accepted from עכו"ם because it is like bringing a קרבן, which עכו"ם may do.
