Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 51

Sanskrit:

स एष भगवान् राजन्व्यतनोद्विहतं यश: ।पुरा रुद्रस्य देवस्य मयेनानन्तमायिना ॥ ५१ ॥

ITRANS:

sa eṣa bhagavān rājanvyatanod vihataṁ yaśaḥpurā rudrasya devasyamayenānanta-māyinā

Translation:

My dear King Yudhiṣṭhira, long, long ago in history, a demon known as Maya Dānava, who was very expert in technical knowledge, reduced the reputation of Lord Śiva. In that situation, Kṛṣṇa, the Supreme Personality of Godhead, saved Lord Śiva.

Purport:

Lord Śiva is known as Mahādeva, the most exalted demigod. Thus Viśvanātha Cakravartī Ṭhākura says that although Lord Brahmā did not know the glories of the Supreme Personality of Godhead, Lord Śiva could have known them. This historical incident proves that Lord Śiva derives power from Lord Kṛṣṇa, the Parabrahman.
