Mishna Bava Metzia 2: אלו מציאות

(1) If you see your fellow Israelite’s ox or sheep gone astray, do not ignore it; you must take it back to your peer. (2) If your fellow Israelite does not live near you or you do not know who [the owner] is, you shall bring it home and it shall remain with you until your peer claims it; then you shall give it back. (3) You shall do the same with that person’s ass; you shall do the same with that person’s garment; and so too shall you do with anything that your fellow Israelite loses and you find: you must not remain indifferent. (4) If you see your fellow Israelite’s ass or ox fallen on the road, do not ignore it; you must raise it together.

The garment was also included in the generalization that one must return all of these items. And why did it emerge from the generalization that is should be specified? To draw an analogy to it and to say to you: What is notable about a garment? It is notable in that there are distinguishing marks concerning it and it has claimants asserting ownership, and its finder is obligated to proclaim his find. So too with regard to any item concerning which there are distinguishing marks and it has claimants asserting ownership, its finder is obligated to proclaim his find.

(1) R. Yishmael says: The Torah is expounded by thirteen hermeneutical principles:

General-specific-general--You may infer only cases that are similar to the specific case.

See Frank pp. 125.

(1) Which found items belong to him, and for which is he obligated to proclaim?These found items belong to him: If one found scattered produce, scattered coins, bundles of grain in a public area, round cakes of pressed figs, baker’s loaves, strings of fish, cuts of meat, unprocessed wool fleeces that are taken from their state of origin directly after shearing, bound flax stalks, or bound strips of combed purple wool, these belong to him. This is the statement of Rabbi Meir. Rabbi Yehuda says: If one finds any lost item in which there is an alteration, he is obligated to proclaim his find. How so? If he found a round cake of pressed figs with an earthenware shard inside it or a loaf of bread with coins inside it. Rabbi Shimon ben Elazar says: If one finds any anpurya vessels, since their shape is uniform and they are indistinguishable, he is not obligated to proclaim his find.

(2) And for these found items, one is obligated to proclaim his find: If one found produce inside a vessel, or a vessel by itself; coins inside a pouch, or a pouch by itself; piles of produce; piles of coins, three coins stacked one atop another; bundles of grain in a secluded area; loaves of a homeowner, wool fleeces that are taken from the house of a craftsman, jugs of wine; or jugs of oil. If one finds any of these, he is obligated to proclaim his find.

(7) If a claimant accurately stated what type of item the lost item that was found by another is, but did not state, i.e., describe, its distinguishing marks, the finder shall not give it to him. And in the case of a swindler, even though he stated its distinguishing marks, the finder shall not give the lost item to him, as it is stated: “And if your brother be not near you, and you know him not, then you shall bring it into your house, and it shall be with you until your brother claims [derosh] it [oto], and you shall return it to him” (Deuteronomy 22:2). You shall not return the lost item until you scrutinize [shetidrosh] your brother to determine whether he, the claimant, is a swindler or whether he is not a swindler. If one finds any living being that works and generates enough revenue to cover the costs of the food that it eats, it shall work and eat while in the finder’s possession. And any living being that does not work but it does eat shall be sold, as it is stated: “Then you shall bring it into your house, and it shall be with you until your brother claims it, and you shall return it to him” (Deuteronomy 22:2), One must see how best to return it to him (including return of its value). If sold, what shall be done with the money received from the sale of the animal? Rabbi Tarfon says: The finder may use it; therefore, if the money is lost, he is liable to pay restitution for it. Rabbi Akiva says: He may not use the money; therefore, if it is lost, he is not liable to pay restitution for it.

(11) If one finds his lost item and his father’s lost item, tending to his own lost item takes precedence. Similarly, if one finds his lost item and his teacher’s lost item, tending to his own lost item takes precedence. If one finds his father’s lost item and his teacher’s lost item, tending to his teacher’s lost item takes precedence, as his father brought him into this world, and his teacher, who taught him the wisdom of Torah, brings him to life in the World-to-Come. And if his father is a Torah scholar, then his father’s lost item takes precedence. If his father and his teacher were each carrying a burden and he wants to assist them in putting down their burdens, he first places his teacher’s burden down and thereafter places his father’s burden down. If his father and his teacher were in captivity, he first redeems his teacher and thereafter redeems his father. And if his father is a Torah scholar, he first redeems his father and thereafter redeems his teacher.
