1.187.9

vayaṃ hi kṣatriyā rājanpāṇḍoḥ putrā mahātmanaḥ |
jyeṣṭhaṃ māṃ viddhi kaunteyaṃ bhīmasenārjunāvimau |
yābhyāṃ tava sutā rājannirjitā rājasaṃsadi || 9 ||

"Hearing these words of Drupada, Yudhishthira answered, saying 'Be not cheerless, O king; let joy fill thy heart! The desire cherished by thee hath certainly been accomplished. We are Kshatriyas, O king, and sons of the illustrious Pandu. Know me to be the eldest of the sons of Kunti and these to be Bhima and Arjuna. By these, O king, was thy daughter won amid the concourse of monarchs. The twins (Nakula and Sahadeva) and Kunti wait where Krishna is. O bull amongst men, let grief be driven from thy heart, for we are Kshatriyas. Thy daughter, O monarch, hath like a lotus been transferred only from one lake into another. O king, thou art our revered superior and chief refuge. I have told thee the whole truth.'
