Mahabharata Santi Parva Chapter 169:2

Mahabharata Santi Parva (Apaddharmanusasana Parva) Chapter 169:2 He was a prince of Cranes, possessed of great wisdom, and a son of (the sage) Kasyapa. He was also known extensively on earth by the name of Rajadharman. Indeed, he surpassed everyone on earth in fame and wisdom. The child of a celestial maiden, possessed of great beauty and learning, he resembled a celestial in splendour. Adorned with the many ornaments that he wore and that were as brilliant as the sun himself, that child of a celestial girl seemed to blaze with beauty. Beholding that bird arrived at that spot, Gautama became filled with wonder. Exhausted with hunger and thirst, the Brahmana began to cast his eyes on the bird from desire of slaying him. Rajadharman said, 'Welcome, O Brahmana! By good luck have I got thee today in my abode. The sun is set. The evening twilight is come. Having come to my abode, thou art today my dear and excellent guest. Having received my worship according to the rites laid down in the scriptures, thou mayst go whither thou wilt tomorrow morning.'
