Vaishnava Samhita. Narasimha Mehta Charitam II. Vol III Book VI Chp 16 Shlokas 14 - 15

नरसिह्मेधा उवाच 
तथास्तु धनमेतन्मे प्रयच्छत सतां वराः |
प्रापयिश्याम्यहं तद्वो द्वारकायां न संशयः ||
पण्यशालास्ति मे तत्र कार्यदर्शी च कश्चन |
दास्यामि पत्रं तस्मै च स वै दास्यति वो धनम् ||

Narasimha Mehta replied

Oh! Sadhus! I shall do as you please. Give me the money. Certainly I shall arrange to forward the same to you at Dwarak. I own a business house at Dwaraka. I have a secretary there. I shall write a letter and instruct him to give you the money there.
