When there is an olive-sized portion of a human corpse in the mouth of a raven and there is a doubt whether or not it flew over a person or keilim in a private domain, the person is impure because of the doubt, provided he has the knowledge to respond to questions. The keilim are pure, because they do not have the capacity to respond to questions. Similarly, when a person was drawing water with one container and pouring it into ten others and the carcass of a creeping animal was found in one of the ten, that container is impure and the others are pure. Although there is a question whether they are all impure, for perhaps the the carcass of the creeping animal had been in the container used to draw water, we rule leniently, because keilim are involved and they do not have the capacity to respond to questions. If the container with which he drew the water possessed a rim, since it is possible for the water to have been poured out, but for the carcass of the creeping animal to have remained, they are all impure. Similarly, when one draws water with ten buckets, one after the other, and pours the water into ten containers, each bucket into a separate container, and it is not known which container was first and which was last, if the carcass of a creeping animal was found in one of them, the other nine containers and the ten buckets are pure, for one could say perhaps the carcass of the creeping animal was in the container originally. If the buckets have rims, all of the buckets and all of the containers are impure. When one pours from one container to another and the carcass of a creeping animal is found in the lower container, the upper container is pure. We do not say that it fell from the upper container. Instead, it is possible that it had been in the lower container. The rationale for this leniency is that keilim are involved and they do not have the capacity of responding to questions. Similar laws apply in all analogous situations.
