Que la neguilla no se trillará con trillo, ni sobre el comino rodará rueda de carreta; sino que con un palo se sacude la neguilla, y el comino con una vara.
Rashi on Isaiah
with a grooved [implement] That is a wooden implement, made with grooves, and its name is מוֹרַג, a threshing-board, and one cuts the straw with it to be straw fodder.
Ibn Ezra on Isaiah
בחרוץ With a threshing instrument. Comp. 41:15.
Rashi on Isaiah
For not with a grooved [implement] do they thresh the black cumin, for its seed is easily extracted from within its straw, and, likewise, on cumin they do not turn the wheel of a wagon to thresh it, because the black cumin is easily beaten with a staff and the cumin with a rod.
