Hashavas Aveida: Hashkafa and Definition

If you see your fellow’s ox or sheep gone astray, do not ignore it; you must take it back to your fellow.

If your fellow does not live near you or you do not know who he is, you shall bring it home and it shall remain with you until your fellow claims it; then you shall give it back to him.

You shall do the same with his ass; you shall do the same with his garment; and so too shall you do with anything that your fellow loses and you find: you must not remain indifferent.

לא תראה את שור אחיך או את שיו נדחים, "You shall not see the ox of your brother or his sheep cast off, etc." This paragraph is an allusion to the need for the scholars to admonish the plain people in order for them to become the true people of the Lord. The term used by the Torah to describe these morally upright righteous people is אחים, brothers. I have already explained to you that this appellation is reserved for the finest group of individuals (compare Shemot Rabbah 52,5). It is these people whom G'd commanded that when they see an "ox" who is lost, i.e. a human being on a lesser moral level who is compared to a beast, to engage in rescuing him. The reason the Torah speaks of "ox and sheep" instead of donkeys, for instance, is that the Jewish people whom the Torah alludes to by the words "ox or sheep" are basically sacred, fit for the altar as opposed to such animals as the donkey. The word אחיך, "your brother," is a simile for G'd who "owns" all of us. The reason that Moses employs this unlikely sounding simile is that the Torah wanted to make plain to which one of His holy people the commandment to restore lost Jewish souls applies, i.e. to the righteous, the Torah scholars.

נרחים, "gone astray;" the word is used in a similar sense in Deut 4,19: "and you are drawn astray." Someone who violates G'd's commandments is considered as having gone astray. The Torah commands that we must not ignore such people but bring them back to one's "brother" i.e. to G'd. The reason the Torah repeats the instruction השב תשיבם, "you shall surely restore them" is that if you will make the first move in setting such people on the right path they will complete the journey back to G'd under their own steam.

ואם לא קרוב אחיך, "And if your brother is not near, etc." Here the Torah hints that it speaks of a period during our final exile, when we will be quite estranged to our Father in Heaven. The period described is the one of which Bileam spoke in Numbers 24,17 when he said: "I can see it but it is not near." The very fact that the redemption does not seem near at hand is apt to estrange the Jewish people to G'd. Even in the present generation the knowledge that the ultimate redemption is so far away undermines the people's faith in G'd. Nonetheless G'd commands ואספתו אל תוך ביתך, "you are to gather him inside your house." The house the Torah speaks of is the Torah academy, etc. There you will teach him the paths of Torah so that the light radiated by Torah study will save this person spiritually. This process will continue until G'd is placated and will claim him back, i.e. עד דרש אחיך אתו. The words והשבות לו, "and you will return it to him," mean that your concern for the straying Jew will be accounted for you as if you had rescued him from becoming totally lost.

§ And Rava says: In a case where one saw a sela coin that fell from another, if he took the coin in order to steal it, before the despair of the owner, he violates all of the following mitzvot: He is liable due to the prohibition: “You shall not…rob” (Leviticus 19:13); and due to the positive mitzva, stated with regard to found items, of: “You shall return them to your brother” (Deuteronomy 22:1), and due to the prohibition, stated with regard to one who finds an item: “You may not disregard” (Deuteronomy 22:3). And even if he returned it after the despair of the owner, it is merely a gift that he gave him; and the transgression that he performed, he performed, and he remains in violation of these mitzvot.

The restoration of lost property to a Jew is a positive command, as it is written : "You shall surely take them back to your brother" (Deuteronomy 22:1). Anyone who sees the lost property of a Jew and ignores it, and leaves it there, breaks a prohibitive command as well as a positive command, as it is written: "You must not withhold your help from any ox or sheep of your brother which you see gone astray" (Deuteronomy 22:1). If he has restored it to the owner he has carried out a positive command.

Rava says that the verse: “And so shall you do with every lost item of your brother” (Deuteronomy 22:3), serves to include an obligation to protect your brother from the loss of his land. Rav Ḥananya said to Rava: There is a baraitathat is taught that supports your opinion. If one saw water that is flowing and coming to inundate another’s field, he must establish a barrier before the water in order to preserve the field.
