[The following rules apply with regard to] any animal found between Jerusalem and Migdal Eder or that radius to any other direction. If it is a female [that can be estimated to be] a year old, it is placed in a closed room to die, lest it be a sin-offering. If it [appears to be] two years old, it should be brought as a peace-offering and bread should be brought with it, lest it be a thanksgiving-offering. If a male that [appears to be] two years old is found, there is no way of correcting the situation, for it is possible that it is a guilt-offering whose owner has not yet received atonement. If one found a male animal that is a year old, he should allow it to pasture until it becomes blemished, bring two animals in its stead and make a stipulation, stating: "If the [blemished animal] was a burnt-offering, this is designated as a burnt-offering in place of it. If it was a peace-offering, this is a peace-offering in place of it." He then offers the first as a burnt-offering. Its accompanying offerings should be brought from communal funds. The other should be brought as a peace-offering together with bread, lest it be a thanksgiving-offering. What should be done with the animal that was found? It should be eaten after it contracts a blemish. For even if it was a firstborn offering or a tithe offering, it could be eaten after it was blemished. If it was a Paschal sacrifice whose time had passed, it is considered as a peace-offering. And during the time the Paschal sacrifice [must be offered], everyone is careful regarding it. If one might ask: Maybe it is a guilt-offering of a nazirite or a person purified from tzara'at? These are not frequently found. Therefore [the Sages] showed no concern about them.
