Lulav

Every part of the lulav has a purpose and without them you don’t have a kosher lulav.

If someone sees a neighbor on the street with a lulav and etrog on the eighth day, the rabbis reason, s/he might mistakenly assume that it is still the seventh day (ḥol hamoed), when the lulav and etrog are still needed.

The event also included the ritual shaking of the lulav and etrog.

The rabbi, carrying a lulav palm frond and etrog yellow citrus which protesters said symbolise human connection with the earth in Judaism, said: "This has been something that I have been involved with since the 60s.

The etrog is a small citrus fruit, while the lulav is a palm branch with two types of twigs (hassadim and aravot) attached to it.

For that reason, the rabbis ruled that one should not take the lulav and etrog on the eighth day, even outside of the Land of Israel.

Rabbis may rule that a specific mitzvah from the Torah should not be performed, e.g. blowing the shofar on Shabbat, or taking the lulav and etrog on Shabbat.

Shulchan Aruch, Orach Chayim 668 However, one does not take the lulav and etrog (nor does one sleep in the sukkah according to most opinions) on the eighth day.

The lulav and etrog are not brought to the synagogue on Shabbat.
