Mahabharata Adi Parva (Chaitraratha Parva)

Mahabharata Adi Parva Chapter 168:2 "The Brahmana continued, 'Drona, gifted with great intelligence, was extremely mortified at this, and settling in his mind some means of humiliating the king of the Panchala he went to the capital of the Kurus, called after the name of an elephant. Then Bhishma, taking with him his grandsons, presented them unto the wise son of Bharadwaja as his pupils for instruction, along with various kinds of wealth. Then Drona, desirous of humiliating king Drupada, called together his disciples and addressed them, 'Ye sinless ones, it behoveth you, after you have been accomplished in arms, to give me as preceptorial fee something that I cherish in my heart.' Then Arjuna and others said unto their preceptor, 'So be it.'—After a time when the Pandavas became skilled in arms and sure aims, demanding of them his fee, he again told them these words, 'Drupada, the son of Prishata, is the king of Chhatravati. Take away from him his kingdom, and give it unto me.' Then the Pandavas, defeating Drupada in battle and taking him prisoner along with his ministers, offered him unto Drona, who beholding the vanquished monarch, said, 'O king, I again solicit thy friendship; and because none who is not a king deserveth to be the friend of a king, therefore, O Yajnasena, I am resolved to divide thy kingdom amongst ourselves. While thou art the king of the country to the south of Bhagirathi (Ganga), I will rule the country to the north.' "The Brahmana continued, 'The king of the Panchalas, thus addressed by the wise son of Bharadwaja, told that best of Brahmanas and foremost of all persons conversant with weapons, these words, 'O high-souled son of Bharadwaja, blest be thou, let it be so, let there be eternal friendship between us as thou desirest!' Thus addressing each other and establishing a permanent bond between themselves, Drona and the king of Panchala, both of them chastisers of foes, went away to the places they came from. But the thought of that humiliation did not leave the king's mind for a single moment. Sad at heart, the king began to waste away.'"
