||When you come [to work] in your neighbor's standing grain, you may take the ears with your hand. However, you may not lift the sickle [for your own benefit] in your neighbor's grain.
Ki tavo bekamat re'echa vekatafta melilot beyadecha vechermesh lo tanif al kamat re'echa.
(Sifri; Yerushalmi, Maasroth 2:4).
Chermash in Hebrew; see Deuteronomy 16:9.
|for your own benefit|
(Sefer HaMitzvoth, Negative 268; Yad, Sekhiruth 12:3). According to this, the commandment here prohibits the worker from stopping work in order to eat. Others say that it forbids him to make a full meal during his working time (Raavad ibid.).
