Devarim 8:8 ארץ חיטה ושעורה, וגפן ותאנה ורימון; ארץ-זית שמן, ודבש. The Gemara in Berachos 41: says in the name of either Rabbi Yosef or Rabbi Yitzchok that the order of the Brachos would depend on what is written closer to Eretz.
Based on this if one would have Grapes, Figs, Pomegranates, Olives and Dates one would make the Bracha on the Olive since Olives are closer to the word Eretz.
Why is there a need for the second Eretz in this verse? Why could the verse not be set up as follows? ארץ חיטה וזית שמן ושעורה ודבש וגפן ותאנה ורימון and leave out the seemingly extra Eretz?
