Markandeyapurana 75.65

Mārkaṇḍeya spoke:
Then by the power of his austerities the great muni placed the constellation Revatī as before in conjunction with the moon, O brāhman. And full of affection he celebrated his daughter’s marriage accompanied with sacred texts according to rule, and said to his son-in-law again, “Tell me, O king, what shall I give thee as a wedding gift? I will give even that which is hard to he obtained, for irresistible are my austerities.”

The king spoke:
Of Manu Svāyambhuva’s lineage[7] I am sprung, O muni. I choose as gift a sou who shall reign over a manvantara through thy favour.
