Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 4


तत्र गत्वौदनं गोपा याचतास्मद्विसर्जिता: ।कीर्तयन्तो भगवत आर्यस्य मम चाभिधाम् ॥ ४ ॥


tatra gatvaudanaṁ gopāyācatāsmad-visarjitāḥkīrtayanto bhagavataāryasya mama cābhidhām


When you go there, My dear cowherd boys, simply request some food. Declare to them the name of My elder brother, the Supreme Lord Balarāma, and also My name, and explain that you have been sent by Us.


Lord Kṛṣṇa encouraged His boyfriends to request charity without being embarrassed. In case the boys felt they had no right to personally approach such respectable brāhmaṇas, the Lord told them to mention the names of Balarāma and Kṛṣṇa, the holy names of God.
