Vintage Israeli stamps depicting the Seven Species designed by Zvi Narkiss (צבי נרקיס, Israeli, 1921-2010), 1958.
The Seven Species (שבעת המינים, Shiv'at HaMinim) are two grains and five fruits mentioned in the Torah as special produce of the Land of Israel: wheat, barley, grape, fig, pomegranate, olive (oil), and date (honey). These staples were central to the diet of the Jewish people in the Land of Israel in biblical times and hold spiritual significance, as shown by the unique blessing recited after eating them to thank G-d for the land's abundance. Their first fruits were offered as bikkurim in the Temple in Jerusalem.
