Devon Ke Dev...Mahadev S03 E11 Sati's three promises

Sati makes three promises to Lord Shiva: she will obey him at all times; she will never lie to him; and she will never hide anything from him. Rishi Atharva brings his scriptures to Lord Shiva, who declares they will henceforth become the Atharva Veda. Lord Brahma’s sons are angered by this.
