Mbh 2.21.2c

For, O King, that ever victorious monarch observed this vow which was known throughout the Worlds that as soon as he should hear of the arrival of Snataka Brahmanas at his place, should it be even at midnight, he would immediately, O Bharata, come out and grant them an audience. Beholding the strange attire of his guests that best of kings wondered much. For all that, however, he waited on them respectfully. Those bulls among men, those slayers of all foes, on the other hand, O thou best of the Bharata race, beholding king Jarasandha, said,--‘Let salvation be attained by thee, O king, without difficulty.’ And, O tiger among kings, having said this unto the monarch, they stood looking at each other. And, O king of kings, Jarasandha then said unto those sons of Pandu and him of the Yadu race, all disguised as Brahmanas--‘Take your seats.’ And those bulls among men sat themselves down, and like the three priests of a great sacrifice blazed forth in their beauty. And king Jarasandha, O thou of the Kuru race, firmly devoted to truth, censuring the disguised guests, said unto them,--‘It is well known to me that in the whole world Brahmanas in the observance of Snataka vow never deck their persons with garlands and fragrant paste unseasonably. Who are ye, therefore, thus decked with flowers, and with hands bearing the marks of the bow-string? Attired in coloured robes and decked unseasonably with flowers and paste, ye give me to understand that ye are Brahmanas, although ye bear Kshatriya energy. Tell me truly who ye are. Truth decks even kings. Breaking down the peak of the Chaityaka hill, why have ye, in disguise, entered (the city) by an improper gate without fear of the royal wrath? The energy of a Brahmana dwelleth in his speech, (not in act). This your feat is not suited to the order to which ye profess to belong. Tell us therefore, the end ye have in view. Arrived here by such an improper way, why accept ye not the worship I offer?
