Vaishnava Samhita. Narasimha Mehta Charitam III. Vol III Book VI Chp 17 Shlokas 18 - 20

अजानन्ती परं देवं पत्नी तस्य महात्मनः |
शुश्रूषां बहुधा चक्रे स्मरन्ती पतिमेव तम् ||
संपन्नं सकलं वस्तु स्थिरा भव गृहे प्रिये |
बृन्दारण्यमहं यामि मां द्रक्ष्यस्यचिरादिह ||
इत्युक्त्वा सान्त्वयन् कृष्णो भक्तभार्यां कृपानिधिः |
बालकाल्लायंश्चैवं तत्रैवान्तरधाद्धरिः ||

All essential things are available at home. Don't go out of the house. I shall be back soon". The repository of mercy, Shri Krishna, thus pacified the bhakta's wife, showered affection on the children and vanished.
