Two nazirites to whom someone says, “I saw one of you defiled, but I do not know which of you it was,” [Both] must shave and [together] bring sacrifices for defilement and sacrifices [for completing a naziriteship] in purity, [and one of them] must say, “If I am unclean, the sacrifices for defilement are mine, and the sacrifices in purity are yours, whereas if I am the one who is clean, the sacrifices in purity are mine and the sacrifices for defilement are yours.” And they must then count thirty [more] days and bring sacrifices in purity and [one of them] must say, “If I am the one who was unclean, the sacrifices for defilement were mine, the sacrifices in purity were yours, and these are my sacrifices in purity, whereas if I was the one who was clean, the sacrifices in purity were mine, the sacrifices for defilement were yours, and these are your sacrifices in purity.” If one of them dies: Rabbi Joshua said that [the other] should request that someone from the marketplace take a nazirite vow together with him, and say: “If I am unclean, you are to be a nazirite immediately, but if I was clean, you are to become a nazirite at the end of thirty days.” They then count thirty days and bring sacrifices for defilement and sacrifices [for completing a naziriteship] in purity and [the first one] says, “If I am the one who was unclean, the sacrifices for defilement are mine and the sacrifices in purity are yours, whereas if I am the one who is clean, the sacrifices in purity are mine and the sacrifices for defilement are [sacrifices offered] in doubt.” They then count [another] thirty days and bring [one set of] the sacrifices in purity and [the first one] says, “If I am the one who was defiled, the sacrifice for defilement [offered previously] was mine and the sacrifice in purity was yours, and this is my sacrifice in purity, whereas if I was the one who was clean, the sacrifice in purity was mine and the sacrifice for defilement [was offered] in doubt and this is your sacrifice in purity.” Ben Zoma said to him: Who will listen to him and take a nazirite vow together with him? Rather he must bring a bird as a sin offering and an animal as a burnt offering and say, “If I was defiled, the sin offering is part of my obligation and the burnt offering is a voluntary offering, whereas if I remained clean, the burnt-offering is part of my obligation and the sin offering is [a sacrifice offered] in doubt.” ‘ He must then count thirty days and bring the sacrifices in purity and say, “If I was defiled, the former burnt offering was a voluntary offering and this is part of my obligation, whereas if I remained clean, the former burnt offering was part of my obligation and this is the voluntary one. And these are the rest of my sacrifices.” Rabbi Joshua said: the result is that he brings his sacrifices half at a time! But the Sages agreed with Ben zoma.
