kav of seed is obligated to give a corner to the poor. Rabbi Joshua said land that yields two seah of grain. Rabbi Tarfon said land of at least six handbreadths by six handbreadths. Rabbi Judah ben Betera said land that requires two strokes of a sickle to harvest, and the law is as he spoke. Rabbi Akiva said that one who cultivates land of any size is obligated to give a corner to the poor and the first fruits. The Mishnah taught that the poor could enter a field to collect three times a day — in the morning, at midday, and in the afternoon. Rabban Gamliel taught that they said this only so that landowners should not reduce the number of times that the poor could enter. Rabbi Akiva taught that they said this only so that landowners should not increase the number of times that the poor had to enter. The landowners of Beit Namer used to harvest along a rope and allowed the poor to collect a corner from every row.

If the owner did not separate it from the standing grain, the owner separates it from the sheaves of grain that have been harvested. If the owner did not separate it from the sheaves, the owner separates it from the pile of grain, as long as the owner has not yet smoothed the pile. Once the owner smooths the pile of grain, it becomes obligated in tithes. Therefore, the owner must first tithe the grain and then give a portion of the produce to the poor, so that the poor need not tithe what they receive. The Sages said in the name of Rabbi Ishmael that if the owner did not separate the portion for the poor during any of these stages, and the owner milled the grain and kneaded it into dough, the owner still needed to separate a portion even from the dough and give it to the poor. Even if the owner has harvested the grain, the portion for the poor is still not considered the owner's possession. The Gemara noted that includes a superfluous term "by reaping" and reasoned that this must teach
