He prohibited us from eating tender grain from the new [produce] before the end of the sixteenth day of Nissan. And that is His, may He be exalted, saying, "tender grain you shall not eat" (Leviticus 23:14). And they already preceded us with their saying (Keritot 5a), "One who ate bread, parched grain and tender grain is liable [separately] for each and every one." And the regulations of the new grain have already been explained in Chapter 6 of Menachot and in [various] places in Sheviit, Maasrot and Challah. (See Parashat Emor; Mishneh Torah, Forbidden Foods 10.)
