In the first aliyah, the Torah gives the mitzvah of the first fruits. After the people are settled in Israel, a farmer takes the first of the fruits of his crop to the Temple in Jerusalem. He goes together with the other farmers in his area in a joyous festive procession accompanied with music and song, led by an ox with gilded horns.
Upon arrival in the holy city, may it be speedily rebuilt, the farmer gives the first fruits to the priest and says a prescribed statement about how the Jews, from Yakov avinu's time to the present, got to Israel with G-d's help. The farmer then rejoices for all the good that G-d has given him. This is done only with the seven fruits that Israel is praised for. The seven fruits are: Dates, figs, grapes, pomegranates, olives, wheat, and barley.
