That sacrifice spake, 'I dread nakedness.' 'What is unnakedness for thee?' 'Let them strew (sacrificial grass) all round me!' For this reason they strew (sacrificial grass) all round the fire. 'I dread thirst.' 'How art thou to be satiated?' 'May I satiate myself after the priest has been satisfied!' Let him therefore, on the completion of the sacrifice, order that the priest be satisfied; for then he satisfies the sacrifice.
