When thou reapest the corn of thy land, thou shalt not cut down all that is on the face of the earth to the very ground: nor shalt thou gather the ears that remain.

“During the harvest, [the law] forbids owners to gather up the bits which fall from the sheaves and similarly advises that in harvesting something should be left behind unreaped. By this it gives excellent teaching to owners in the practice of generous sharing by leaving some of their property for those in need and providing the poor with a chance for food. Do you see how the law proclaims simultaneously the justice and goodness of God, who provides food unstintingly for all? Again, in the grape harvest the harvesters are forbidden to go back and cut anything that has been left over or to collect fallen grapes. The same rules are applied to olive gatherers. In fact the principle of tithing crops and flocks was an education in honoring the divine. We are not to be totally absorbed by profit but to share humanely with the neighbor as well.”

“לא תכלה פאת שדך THOU SHALT NOT WHOLLY REAP THE CORNER OF THY FIELD — This means that one must leave פאה (an uncut portion) at the extremity of one's field (cf. Sifra, Kedoshim, Chapter 1 9; Mishna Peah 1:2; Shabbat 23a). ולקט קצירך [NEITHER SHALT THOU COLLECT] THE GLEANINGS OF THY HARVEST — Gleanings are ears that drop from the hand of the harvester during the reaping — one or two at a time, but three do not come under the category of לקט (Mishna Peah 6:5; Sanhedrin 99a).”

“And when ye reap the harvest of your land,.... Of the land of Canaan, when come into it, which having sown, and it was harvest, either barley harvest or wheat harvest, or both, and especially the latter, to which reaping seems best to agree: thou shall not wholly reap the corner of the field; but a part was to be left for the poor. This follows upon the peace offerings: and, as Aben Ezra observes, as the fat of them was to be given to God, so somewhat of the harvest was to be given for the glory of God to the poor and stranger. In the Misnah is a whole treatise, called "Peah", which signifies "the corner", in which there are many decisions concerning this affair; and among the rest, whereas it is not fixed in the law how large the corner should be, what quantity should be left, how many ears of corn, or what a proportion of the field, this is there determined by the wise men, who say, they do not leave less than a sixtieth part; for though they say there is no measure (certain) for the corner, yet the whole is according to the largeness of the field, or according to the multitude of the poor, or according to the plenty of the increase (l), so that, as these were, more or less were left: and though the place to be left is called a corner, it was a matter indifferent in what part of the field it was; for so it follows, they give (or leave) the corner at the beginning of the field, or in the middle (m); and Ben Gersom observes, that the corner was at the end of the field, where the harvest is finished; and it is plain where the harvest is finished, he says, the corner should be left; for the law does not precisely determine, only that part of the corner should be left to the poor; and it is of no consequence to the poor whether it is in the middle of the field or in the end of it; but Maimonides (n) thinks it was to be left at the end of the field, that the poor might know where to come for it: and in the above treatise the times are also set when the poor should come and gather it, which they might not do at any time; and there were three times on a day they had leave to come, in the morning, in the middle of the day, and at the evening sacrifice (o), i.e. about three o'clock in the afternoon; the morning was appointed, as the commentators say (p), for the sake of women that had young children, who were then asleep, the middle of the day for the sake of nurses, and the evening for the sake of ancient persons: neither shalt thou gather the gleanings of thy harvest; ears of corn which fall from the hand or sickle of the reaper, or in gathering the reaps to bind up in sheaves. In the above treatise it is asked, what is a gleaning? that which falls in reaping; if the reaper reaps his handful, or plucks up an handful, and a thorn strikes him, and it falls out of his hand to the ground, lo, it is the owner's; but if out of the middle of his hand, or out of the middle of the sickle, it is the poor's; if from the further part of his hand, or of the sickle, it is the owner's; but if from the top of his hand (or tip of his fingers) or the point of the sickle, it is the poor's (q): and it is further said (r),"two ears are a gleaning, but three are not,''and so Jarchi on the text, that is, when three fall together; this is according to the school of Hillel, but according to the school of Shammai, if there were three ears that fell together, they were the poor's, if four they belonged to the owner.

“When ye reap the harvest - Liberty for the poor to glean both the corn-fields and vineyards was a Divine institution among the Jews; for the whole of the Mosaic dispensation, like the Christian, breathed love to God and benevolence to man. The poor in Judea were to live by gleanings from the corn-fields and vine yards. To the honor of the public and charitable spirit of the English, this merciful law is in general as much attended to as if it had been incorporated with the Gospel.”

“And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field--The right of the poor in Israel to glean after reapers, as well as to the unreaped corners of the field, was secured by a positive statute; and this, in addition to other enactments connected with the ceremonial law, formed a beneficial provision for their support. At the same time, proprietors were not obliged to admit them into the field until the grain had been carried off the field; and they seem also to have been left at liberty to choose the poor whom they deemed the most deserving or needful (Rut 2:2, Rut 2:8). This was the earliest law for the benefit of the poor that we read of in the code of any people; and it combined in admirable union the obligation of a public duty with the exercise of private and voluntary benevolence at a time when the hearts of the rich would be strongly inclined to liberality.”

“Laws concerning the conduct towards one's neighbour, which should flow from unselfish love, especially with regard to the poor and distressed. Lev 19:9-10 In reaping the field, "thou shalt not finish to reap the edge of thy field," i.e., not reap the field to the extreme edge; "neither shalt thou hold a gathering up (gleaning) of thy harvest," i.e., not gather together the ears left upon the field in the reaping. In the vineyard and olive-plantation, also, they were not to have any gleaning, or gather up what was strewn about (peret signifies the grapes and olives that had fallen off), but to leave them for the distressed and the foreigner, that he might also share in the harvest and gathering. כּרם, lit., a noble plantation, generally signifies a vineyard; but it is also applied to an olive-plantation (Jdg 15:5), and her it is to be understood of both. For when this command is repeated in Deu 24:20-21, both vineyards and olive-plantations are mentioned. When the olives had been gathered by being knocked off with sticks, the custom of shaking the boughs (פּאר) to get at those olives which could not be reached with the sticks was expressly forbidden, in the interest of the strangers, orphans, and widows, as well as gleaning after the vintage. The command with regard to the corn-harvest is repeated again in the law for the feast of Weeks or Harvest Feast (Lev 23:20); and in Deu 24:19 it is extended, quite in the spirit of our law, so far as to forbid fetching a sheaf that had been overlooked in the field, and to order it to be left for the needy. (Compare with this Deu 23:24-25.) Lev 19:11-13 The Israelites were not to steal (Exo 20:15); nor to deny, viz., anything entrusted to them or found (Lev 6:2.); nor to lie to a neighbour, i.e., with regard to property or goods, for the purpose of overreaching and cheating him; nor to swear by the name of Jehovah to lie and defraud, and so profane the name of God (see Exo 20:7, Exo 20:16); nor to oppress and rob a neighbour (cf. Lev 6:2), by the unjust abstraction or detention of what belonged to him or was due to him, - for example, they were not to keep the wages of a day-labourer over night, but to pay him every day before sunset (Deu 24:14-15). Lev 19:14 They were not to do an injury to an infirm person: neither to ridicule or curse the deaf, who could not hear the ridicule or curse, and therefore could not defend himself (Psa 38:15); nor "to put a stumblingblock before the blind," i.e., to put anything in his way over which he might stumble and fall (compare Deu 27:18, where a curse is pronounced upon the man who should lead the blind astray). But they were to "fear before God," who hears, and sees, and will punish every act of wrong (cf. Lev 19:32, Lev 25:17, Lev 25:36, Lev 25:43). Lev 19:15 In judgment, i.e., in the administration of justice, they were to do no unrighteousness: neither to respect the person of the poor (πρόσωπον λαμβάνειν, to do anything out of regard to a person, used in a good sense in Gen 19:21, in a bad sense here, namely, to act partially from unmanly pity); nor to adorn the person of the great (i.e., powerful, distinguished, exalted), i.e., to favour him in a judicial decision (see at Exo 23:3). Lev 19:16 They were not to go about as calumniators among their countrymen, to bring their neighbour to destruction (Eze 22:9); nor to set themselves against the blood of a neighbour, i.e., to seek his life. רכיל does not mean calumny, but, according to its formation, a calumniator (Ewald, 149e). Lev 19:17 They were not to cherish hatred in their hearts towards their brother, but to admonish a neighbour, i.e., to tell him openly what they had against him, and reprove him for his conduct, just as Christ teaches His disciples in Mat 18:15-17, and "not to load a sin upon themselves." חטא עליו נשׁא does not mean to have to bear, or atone for a sin on his account (Onkelos, Knobel, etc.), but, as in Lev 22:9; Num 18:32, to bring sin upon one's self, which one then has to bear, or atone for; so also in Num 18:22, חטא שׂאת, from which the meaning "to bear," i.e., atone for sin, or suffer its consequences, was first derived. Lev 19:18 Lastly, they were not to avenge themselves, or bear malice against the sons of their nation (their countrymen), but to love their neighbour as themselves. נטר to watch for (Sol 1:6; Sol 8:11, Sol 8:12), hence (= τηρεῖν) to cherish a design upon a person, or bear him malice (Psa 103:9; Jer 3:5, Jer 3:12; Nah 1:2).”
