English

If a heathen prince donates money for Jewish Charities, the money should be accepted for the sake of peace; but it should be distributed among non-Jewish poor secretly so that the prince might not hear of it. RMI.—Some hold that if he specified the purpose, the money should be devoted to that purpose. But donations towards the erection of a synagogue are always accepted.
