Mbh 5.118.1a

“Narada said, ‘The illustrious Madhavi, faithful to her promise, abandoning that prosperity and once more becoming a maiden, followed the footsteps of the Brahmana Galava. And Galava, whose heart was set upon the accomplishment of his own business, reflecting upon what he should do next then went to the city of the Bhojas for waiting upon king Usinara. And arrived before that king of unbaffled prowess, Galava addressed him, saying, “This maiden will bear thee two royal sons. And, O king, begetting upon her two sons equal unto the Sun and the Moon, thou mayst attain all thy objects both here and hereafter. As her dower, however, O thou that art conversant with every duty, thou shalt have to give me four hundred steeds of lunar splendour, each having ear black of hue. This effort of mine for obtaining the steeds is only on account of my preceptor, otherwise I myself have nothing to do with them. If thou art able to accept (my terms), do as I bid thee without any hesitation. O royal sage, thou art now childless. Beget, O king, a couple of children. With offspring so begot as a raft, save they Pitris and thyself also. O royal sage, he that hath fruit in the shape of offspring to enjoy, never falleth from heaven. Nor hath such a person to go to that frightful hell whither the childless are doomed to go.” Hearing these and other words of Galava, king Usinara, replied unto him, saying, “I have heard what thou, O Galava, hast said. My heart also is inclined to do thy bidding. The Supreme Ordainer, however, is all-powerful. I have only two hundred steeds of the kind indicated by thee, O best of Brahmanas. Of other kinds, I have many thousands moving about in my dominions. I will, O Galava, beget only one son upon her, by treading the path that hath been told by others such as Haryyaswa and Divodasa. I will act after their manner in the matter of the dower.
