Mbh 3.37.2a

Vaisampayana continued, “Having said this, the exalted Yudhishthira the just, imparted that science unto Arjuna. And the elder brother having communicated with due rites the knowledge unto his heroic brother, with speech and body and mind under perfect control, commanded him to depart. And at the command of Yudhishthira, the strong-armed Arjuna, taking up the Gandiva as also his inexhaustible quivers, and accoutred in mail and gauntlets and finger-protectors made of the skin of the guana, and having poured oblations into the fire and made the Brahmanas to utter benedictions after gifts, set out (from Kamyaka) with the objects of beholding Indra. And armed with the bow, the hero, at the time of setting out heaved a sigh and cast a look upwards for achieving the death of Dhritarashtra’s sons. And beholding Kunti’s son thus armed and about to set out, the Brahmanas and Siddhas and invisible spirits addressed him, saying, ‘O son of Kunti, obtain thou soon what thou wishest.’ And the Brahmanas, also uttering benedictions said, ‘Achieve thou the object thou hast in view. Let victory be truly thine.’ And beholding the heroic Arjuna, of thighs stout as the trunks of the Sala, about to set out taking away with him the hearts of all, Krishna addressed him saying, ‘O thou strong-armed one, let all that Kunti had desired at thy birth, and let all that thou desirest, be accomplished, O Dhananjaya! Let no one amongst us be ever again born in the order of Kshatriyas. I always bow down unto the Brahmanas whose mode of living is mendicancy. This is my great grief that the wretch Duryodhana beholding me in the assembly of princes mockingly called me a cow! Besides this he told me in the midst of that assembly many other hard things. But the grief I experience at parting with thee is far greater than any I felt at those insults. Certainly, in thy absence, thy brothers will while away their waking hours in repeatedly talking of thy heroic deeds!
