Mahabharata Adi Parva Chapter 99:2

Mahabharata Adi Parva Chapter 99:2 Therefore, O best of celestials, bring that cow so that my friend drinking of her milk may alone become on earth free from disease and decrepitude. O illustrious and blameless one, it behoveth thee to grant me this desire of mine. There is nothing that would be more agreeable to me.' On hearing these words of his wife, Dyu, moved by the desire of humouring her, stole that cow, aided by his brothers Prithu and the others. Indeed, Dyu, commanded by his lotus-eyed wife, did her bidding, forgetting at the moment the high ascetic merits of the Rishi who owned her. He did not think at the time that he was going to fall by committing the sin of stealing the cow. "When the son of Varuna returned to his asylum in the evening with fruits he had collected, he beheld not the cow with her calf there. He began to search for them in the woods, but when the great ascetic of superior intelligence found not his cow on search, he saw by his ascetic vision that she had been stolen by the Vasus. His wrath was instantly kindled and he cursed the Vasus, saying, 'Because the Vasus have stolen my cow of sweet milk and handsome tail, therefore, shall they certainly be born on earth!' "O thou bull of Bharata's race, the illustrious Rishi Apava thus cursed the Vasus in wrath. And having cursed them, the illustrious one set his heart once more on ascetic meditation. And after that Brahmarshi of great power and ascetic wealth had thus in wrath cursed the Vasus, the latter, O king, coming to know of it, speedily came into his asylum. And addressing the Rishi, O bull among kings, they endeavoured to pacify him. But they failed, O tiger among men, to obtain grace from Apava—that Rishi conversant, with all rules of virtue. The virtuous Apava, however, said, 'Ye Vasus, with Dhava and others, ye have been cursed by me. But ye shall be freed from my curse within a year of your birth among men. But he for whose deed ye have been cursed by me he, viz., Dyu, shall for his sinful act, have to dwell on earth for a length of time. I shall not make futile the words I have uttered in wrath. Dyu, though dwelling on Earth, shall not beget children. He shall, however, be virtuous and conversant with the scriptures. He shall be an obedient son to his father, but he shall have to abstain from the pleasure of female companionship.' "Thus addressing the Vasus, the great Rishi went away. The Vasus then together came to me. And, O king, the begged of me the boon that as soon as they would be born, I should throw them into the water.
