Mbh 5.141.1d

The two sons of Madri, Nakula and Sahadeva, of great fame and prowess, will be the slayers of the sacrificial animals; rows of bright cars furnished with standards of variegated hue, will, O Govinda, be stakes (for tying the animals), O Janardana, in this sacrifice. Barbed arrows and Nalikas, and long shafts, and arrows with heads like calf’s tooth, will play the part of spoons (wherewith to distribute the Soma juice) while Tomaras will be the vessels of Soma, and bows will be pavitras. The swords will be Kapalas, the heads (of slain warriors) the Purodasas and the blood of warriors the clarified butter. O Krishna, in this sacrifice, the lances and bright maces (of the warriors) will be pokers (for stirring the sacrificial fire) and the corner stakes (for keeping the fire-wood from falling down). The disciples of Drona and Kripa, the son of Saradwat, will be the Sadasyas (assisting priests). The arrows shot by the wielder of Gandiva and by (other) mighty car-warriors, and by Drona and Drona’s son, will play the part of ladles for distributing the Soma. Satyaki will discharge the duties of the chief assistant of the Adhyaryu. Of this sacrifice, Dhritarashtra’s son will be installed as the performer, while this vast army will be his wife. O thou of mighty arms, when the nocturnal rites of sacrifice will begin, the mighty Ghatotkacha will play the part of the slayer of (devoted) victims. The mighty Dhrishtadyumna, who sprang into life from the sacrificial fire, having for its mouth the rites celebrated with mantras, will, O Krishna, be the Dakshina of that sacrifice. For those harsh words, O Krishna, that I said before unto the sons of Pandu for the gratification of Dhritarashtra’s son,--for that wicked conduct of mine,--I am consumed with repentance. When O Krishna, thou wilt behold me slain by Arjuna, then will the Punachiti of this sacrifice commence.
