פירוש על ביכורים 3:11

ואם אינה באה מן הארץ – such as the case where they brought the supplement from the other side of the Jordan [River], as is taught in the Mishnah above (Chapter 1, Mishnah 10), that they bring from there the First Fruits even though they are not from “the land flowing with milk and honey.” Alternatively, Our Mishnah is according to Rabbi Shimon who said (Chapter 3, Mishnah 9) that we adorn the First Fruits [with fruit] other than the Seven Species, and that law also applies from fruit that grew outside the Land of Israel, and just like according to him, we adorn [the First Fruits] with fruit [grown] outside the Land of Israel, so too, the supplement comes from fruit [grown] outside the Land of Israel. And this comes to – teach us here that the supplement which is not from the Land [of Israel] is not like the First Fruits.

When did they say that the additions to the bikkurim are like bikkurim [themselves]? When they come from the land [of Israel]; but if they do not come from the land, they were not regarded as bikkurim [themselves]. This mishnah clarifies a point in yesterday’s mishnah. Additions to bikkurim have the halakhic status of bikkurim only if they are brought from the land of Israel. If they are brought from outside of the land, for instance from Transjordan which is in according to some opinions liable for bikkurim (see 1:10), then they don’t have the same status as bikkurim. This means they will be liable for demai and they can be eaten while impure.
