The commandment of leaving the peret of the vineyard: To leave the peret of the vineyard to the poor. And that is that which separates and falls from the grapes at the time of the grape harvest, as it is stated (Leviticus 19:10), “to the poor and to the stranger shall you leave them,” after it mentioned, “and the fallen grapes of your vineyard, you shall not gather.”

And I will write all of the matters of the commandment in the negative commandment after this of “do not gather” (Sefer HaChinukh 223), with God’s help.
