Four species

The four species (Hebrew: ארבעת המינים‎ arba'at ha-minim, also called arba'a minim) are four plants—the etrog, lulav, hadass, and aravah—mentioned in the Torah (Leviticus 23:40) as being relevant to the Jewish holiday of Sukkot. Observant Jews tie together three types of branches and one type of fruit and wave them in a special ceremony each day of the Sukkot holiday, excluding Shabbat. According to Rabbinic Judaism, the waving of the four plants is a mitzvah prescribed by the Torah, and it contains symbolic allusions to a Jew's service of God.
