(Mishnah): R. Yehuda says - One may only bind the Lulav using something that grows on a date-palm. (Note: According to the Meleches Shlomo, R. Yehuda would reason that one could also use any product of the Hadas or Aravah trees.)

R. Meir says - one may even bind it with a cord.

R. Meir said that there was once a story of the people of Yerushalayim who bound their Lulavs with golden threads.

The Chachamim replied - they bound it underneath with a string from the date-palm.

When would they shake the four species? In Halel, during the recital of the words 'Hodu L'Hashem', both at the beginning and at the end (the verse Hodu L'Hashem etc. appears twice in Halel).

According to Hilel, one also shakes during the words "Ana Hash-m Hoshiya Na".

According to Beis Shamai, one also shakes during the words "Ana Hash-m Hazlicha Na".

R. Akiva said - I was once looking at Rabban Gamliel and R. Yehoshua - all of the people were shaking their Lulavs, but they only shook during "Ana Hash-m Hoshiya Na".

One who returns from a journey where he did not have a Lulav, when he enters his house he should take the Lulav, even if he must interrupt his meal.

If he did not take it in the morning, he should take it in the afternoon, because the entire day is valid for taking the Lulav.

(Gemara - Question): Did the Tannaim (R. Gamliel and R' Yehoshua) not shake at "Hodu"?

Answer: They did, but R. Akiva was teaching that they did not shake during the words "Ana Hash-m Hatzlicha Na".

Rav Chiya bar Ashi quoting Rav: A person who rises early to travel, (on Sukos) he should take his Lulav and shake it and (on Rosh HaShanah) he should sound his Shofar. When the time of Krias Shema arrives, he should read it and pray (Shemoneh Esrei).

Beraisa: He should shake it three times in each direction.

Question (R. Zeira): Is the movement away from him considered one and bring back considered one, or is moving there and back considered one?

Parallel question: The Mishnah in Nidah teaches about the seven substances that must be rubbed on a blood stain in order to remove it. The Mishnah states that he must rub three times between applying one substance and the next. R. Zeira asked there as well - Is the movement away from him considered one and bring back considered one, or is moving there and back considered one? The Gemara does not answer either question.
