Vishnupurana 4.7.2

4.7.2

amāvasor bhīmo nāma putro 'bhavat ||

PURÚRAVAS had six sons, Áyus, Dhímat, Amávasu, Viśwavasu, Śatáyus, and Śrutáyus. The son of Amávasu was Bhíma; his son was Kánchana; his son was Suhotra, whose son was Jahnu. This prince, whilst performing a sacrifice, saw the whole of the place overflowed by the waters of the Ganges. Highly offended at this intrusion, his eyes red with anger, he united the spirit of sacrifice with himself, by the power of his devotion, and drank up the river. The gods and sages upon this came to him, and appeased his indignation, and reobtained Gangá from him, in the capacity of his daughter (whence she is called Jáhnaví).
