Blessing on the Seven Species ...
with which Israel is blessed ...Rabbi Shmuel Knopfler
While we are required to make a blessing on any food we eat, there are special rules for the “seven species”, the seven kinds of produce mentioned in the Torah as the praise of the Land of Israel:
wheat, barley, grapes, figs, pomegranate, olives, and dates (D’varim 8:8).
These kinds of produce have priority over other kinds in making a first blessing (SA OC 211), and they have a special long after-blessing (“one like three” – SA OC 208).
Rav Natan of Breslav explains how this rule serves to connect all of our blessings to the praise of the Land of Israel.
