Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 22-23

Sanskrit:

श्रीशुक उवाचएवं कृष्णमुपामन्‍त्र्य सुरभि: पयसात्मन: । जलैराकाशगङ्गाया ऐरावतकरोद्‌धृतै: ॥ २२ ॥ इन्द्र: सुरर्षिभि: साकं चोदितो देवमातृभि: । अभ्यसिञ्चत दाशार्हं गोविन्द इति चाभ्यधात् ॥ २३ ॥

ITRANS:

śṛī-śuka uvācaevaṁ kṛṣṇam upāmantryasurabhiḥ payasātmanaḥjalair ākāśa-gaṅgāyāairāvata-karoddhṛtaiḥ

Translation:

Śukadeva Gosvāmī said: Having thus appealed to Lord Kṛṣṇa, mother Surabhi performed His bathing ceremony with her own milk, and Indra, ordered by Aditi and other mothers of the demigods, anointed the Lord with heavenly Gaṅgā water from the trunk of Indra’s elephant carrier, Airāvata. Thus, in the company of the demigods and great sages, Indra coronated Lord Kṛṣṇa, the descendant of Daśārha, and gave Him the name Govinda.

Purport:

According to the ācāryas, because Indra was embarrassed by his blunder of attacking Vṛndāvana, he was reluctant to worship the Lord. Therefore the heavenly mothers, such as Aditi, encouraged him to go ahead and do so. Feeling authorized by the encouragement of demigods less offensive than he, Indra then bathed the Lord. Indra discovered that the beautiful cowherd boy named Kṛṣṇa is indeed the Supreme Personality of Godhead.
