Mbh 2.17.3a

Krishna said,--‘Hear, O monarch, who Jarasandha is; what his energy; and what is his prowess; and why also he hath been spared by us, Even though he hath repeatedly offended us. There was a mighty king of the name of Vrihadratha, the lord of the Magadhas. Proud in battle, he had three Akshauhinis of troops. Handsome and endued with energy, possessed of affluence and prowess beyond measure, and always bearing on his person marks indicating installation at sacrifices. He was like a second Indra. In glory he was like unto Suryya, in forgiveness like unto the Earth, in wrath like unto the destroyer Yama and in wealth like unto Vaisravana. And O thou foremost of the Bharata race, the whole earth was covered by his qualities that descended upon him from a long line of ancestors, like the rays emerging from the sun. And, O bull of the Bharata race, endued with great energy that monarch married two twin daughters of the king of Kasi, both endued with the wealth of beauty. And that bull among men made an engagement in secret with his wives that he would love them equally and would never show a preference for either. And the lord of the earth in the company of his two dearly loved wives, both of whom suited him well, passed his days in joy like a mighty elephant in the company of two cow-elephants, or like the ocean in his personified form between Ganga and Yamuna (also in their personified forms). The monarch’s youth however, passed away in the enjoyment of his possessions, without any son being born unto him to perpetuate his line. The best of monarch failed to obtain a son to perpetuate his race, even by means of various auspicious rites, and homas, and sacrifices performed with the desire for having an offspring. One day the king heard that the high-souled Chanda-kausika, the son of Kakshivat of the illustrious Gautama race, having desisted from ascetic penances had come in course of his wanderings to his capital and had taken his seat under the shade of a mango tree.
