Mbh 12.29.4j

It hath been heard by us that king Gaya obtained all those wishes from Agni. On days of the new moon, on those of the full moon, and on every fourth month, for a thousand years, Gaya repeatedly performed the Horse-sacrifice. Rising (at the completion of every sacrifice) he gave away a hundred thousand kine and hundreds of mules (unto the Brahmanas) during this period. That bull among men gratified the gods with Soma, the Brahmanas with wealth, the Pitris with Swadha, and the women with the accomplishment of all their wishes. In his great Horse-sacrifice, king Gaya caused a golden ground to be made, measuring a hundred cubits in length and fifty in breadth, and gave it away as the sacrificial fee. That foremost of men, viz., Gaya, the son of Amurtarayas, gave away as many kine as there are sand grains, O king, in the river Ganga. When he, O Srinjaya, who far surpassed thee in the four principal attributes and who was purer than thy son, fell a prey to death, do not grieve for thy son that is dead. We hear, O Srinjaya, that Sankriti's son Rantideva also fell a prey to death. Having undergone the austerest of penances and adored him with great reverence, he obtained these boons from Sakra, having solicited them, saying "Let us have abundant food and numerous guests. Let not my faith sustain any diminution, and let us not have to ask anything of any person." The animals, both domestic and wild, slaughtered in his sacrifice, used to come to him, viz., the high-souled Rantideva of rigid vows and great fame, of their own accord. The secretions that flowed from the skins of the animals (slaughtered in his sacrifices), produced a mighty and celebrated river which to this day is known by the name of Charmanwati. King Rantideva used to make gifts unto the Brahmanas in an extensive enclosure. When the king said, "Unto thee I give a hundred nishkas! Unto thee I give a hundred," the Brahmanas (without accepting what was offered) made a noise (expressive of refusal).
