Halakhah su Levitico 19:10

Behold it is already been completely explained that it is inappropriate to count every negative or positive commandment that is found in the Torah, for it [may be] a repetition. Indeed it is appropriate to count [only] the content that we are commanded about or prohibited from. And it is impossible to have knowledge of a repeated negative or positive commandment that is coming to give additional content, without a teacher that instructs it. And [these teachers] are those that received the traditional explanation, peace be upon them. And do not err also because the prohibition is repeated with different words - like His, may He be exalted, saying (Leviticus 19:10), "You shall not pick (teollel) your vineyard bare," once He also said (Deuteronomy 24:19), "and overlook a sheaf in the field, do not turn back to get it," and He said (Deuteronomy 24:20), "When you beat down the fruit of your olive trees, do not extract (tefaer) again." For these are not two negative commandments, but rather one prohibition about one matter - and that is that he not take that which he overlooked from the grain or the fruits when he gathers them. And He brought two examples about them - from grapes and from olives. And He called what is left of the grapes ollelot; and of the olives, "pe'erot. And the understanding of tefaer is do not remove that which you have overlooked in some of your pe'erot - and those are the branches. (See the glosses on this book.) And to this principle, it is appropriate to attach that which I will [now] say. And that is that when I say that it is appropriate that they count the content about which we are commanded or from which we are prohibited, it is on condition that the content that we are prohibited is a separate negative commandment for each and every matter; or that the transmitters [present] a proof that separates one matter from another and that each of them requires [its own] prohibition. However when there is one negative commandment that includes many matters, only that negative commandment is counted, and not all of the content that is included in that negative commandment. And this is a general prohibition, for which we do not give lashes - as we will now explain. And that is that they said (Sanhedrin 63a) in explanation of His saying, "You shall not eat upon the blood" (Leviticus 19:26), "From where [do we know] that one who eats from an animal before its soul departs is in [transgression of] a negative commandment? As it is stated, 'You shall not eat upon the blood.' Another matter: From where is it derived that one who eats the meat of an offering before the blood has been sprinkled [on the altar] is in [transgression of] a negative commandment? We learn to say,'You shall not eat upon the blood' - you shall not eat the meat when the blood is still in the bowl. Rabbi Dosa says, 'From where [do we know] that we do not provide a meal for mourners of those executed by the court? We learn to say, "You shall not eat upon the blood."' Rabbi Akiva says, 'From where [do we know] that a Sanhedrin that killed a soul (i.e., that sentenced a person to death) may not taste anything that entire day? We learn to say, "You shall not eat upon the blood."' Rabbi Yochanan says, 'From where [do we know] the prohibition against the behavior of a stubborn and rebellious son? We learn to say, "You shall not eat upon the blood."'" Behold that we are prohibited from all of these five things, but they they are all included under one negative commandment. And they also said (Berakhot 10b), "From where [do we know] that a person should not taste anything until he prays? We learn to say, 'You shall not eat upon the blood' - you may not eat before you pray for your blood." And in explanation, they said in the Gemara (Sanhedrin 63a), "For all of [these specific prohibitions], he is not given lashes - as it is a general negative commandment." And they also explained that a general negative commandment is when two or three prohibitions come from one negative commandment. So it is inappropriate that they should count each and every prohibition it included as a separate negative commandment; but rather only the one negative commandment that includes all of them. And similar to this negative commandment - meaning, "You shall not eat upon the blood," - is His saying, "you shall not place a stumbling block before the blind" (Leviticus 19:14). As it also includes many matters, as will be explained (Sefer HaMitzvot, Negative Commandments 299). And likewise, His saying, "You must not carry a false rumor" (Exodus 23:1) - behold, it too includes many matters, as will be explained (Sefer HaMitzvot, Negative Commandments 281). And this is one of the types of general negative commandments.

To leave over the corner of the field: To leave over a corner from the produce, as it is stated (Leviticus 19:10), "to the poor and to the stranger shall you leave them," after it mentioned, "you shall not finish the corner of your field" (Leviticus 19:9). And the understanding of stranger [here] is a righteous convert (see Sifra Kedoshim 3:4). And so [too], any "stranger" stated in [the context of] gifts to the poor - as behold, it is written about the second tithe (Deuteronomy 26:12), "to the stranger, to the orphan and to the widow." And that is certainly the righteous convert - when undifferentiated - as its witnesses (the orphan and the widow) are by its side. And the same is the case for all of the gifts to the poor. And nonetheless they, may their memory be blessed, said (Gittin 59b) that we do not prevent them from the poor of the idolaters, due to the ways of peace. And the content of the corner, is that a person leaves a little of his produce at the end of his field at the time that he reaps. And there is no measure to this remnant by Torah writ, but the Sages gave a measurement to the thing (Mishnah Peah 1:2), and it is one in sixty parts.

To not finish the corner in the field: Not to harvest all of what is planted, but rather to leave a remnant from it to the poor in the edge of the field, as it is stated (Leviticus 19:9), "you shall not finish the corner of your field in your harvesting." And this negative commandment is rectified by a positive commandment, as it is stated (Leviticus 19:10), "to the poor and to the stranger shall you leave them, etc." - meaning to say, that if he transgressed and harvested all of the field, that he give the measure of the corner to the poor from that which is harvested. And that is rabbinically one in sixty parts, as they obligated us so; but from the Torah, it has no measure, as we learned in Mishnah Peah 1:1, "These are the things that do not have a measure: the corner, etc."
