5 And so it is with peret [separated fruit] that fell from the vine at the time of harvesting and with olélot [malformed grape clusters], as it is said, (Lev. 19:10) You shall not pick your vineyard bare [te'olél] or gather the fallen fruit [uferet] of your vineyard; you shall leave them for the poor and the stranger. So also with one who stacks sheaves and has forgotten a sheaf in the field. This person may not recover it, as it is said, (Deut. 24:19) And overlook a sheaf in the field, do not turn back to get it. If one does transgress [the negative mitzvah against picking up a forgotten sheaf] and gleans and even grinds and bakes, this one still must give to the poor, as it is said, (Deut. 24:19) It shall go to the stranger, the fatherless, and the widow. This is a positive mitzvah. Thus you learn that all these mitzvot are negative which are transformed into positive mitzvot, and if one does not fulfill a positive mitzvah, one deserves punishment.
